3 Day Potty Training Method: How to Potty Train in 3 Days

Sharing is caring!

Ohhhhhh, potty training. The joys. Potty training is one of my least favorite parts of parenting… at least out of everything I’ve experienced so far. But if you want to know all about the 3 day potty training method, you’ve come to the right place: we followed the 3-day potty training method with our son, Theo, and it worked like a charm.

Will the three day potty training process work for your toddler? That’s not a black and white answer because each child is so completely unique.

The 3-day potty training method worked amazingly well for our firstborn, and I’ll give you all of the details below on how to potty train in 3 days so you can figure out if it’s right for your family, plus a lot of potty training tips in general!

At What Age Should You Start the 3-Day Potty Training Method?

I am a big believer in potty training on the later side.

(Read more about the benefits of potty training late.)

I don’t like drawing things out and prefer to get them over with as quickly as possible. The sooner we can have potty training success, the better, in my book! Even if that means basically being stuck at home and watching your child like a hawk for 3 days.

We waited to potty train late, but then did it cold turkey; naptime potty training, nighttime potty training, no pullups or training pants, etc.

Only you can know what’s truly best.

I also have many friends who have potty trained early and it has worked so well for them.

This is just proof that potty training is not a one size fits all (as is most of parenting!), just like raising kids isn’t one size fits all!

If you’re interested in potty training early, you may like to read my friend Katrina’s post on her 10-step potty training method.

Theo’s Birthday is in January and we potty trained him the Thanksgiving weekend before his 3rd Birthday, so he was 2 and 10 months.

I chose Thanksgiving weekend because my husband was home and we could tackle toilet training together using the three day method.

We also went out to get our Christmas Tree early Friday morning, so it was fun to stay home and decorate our tree and watch Christmas movies while we were potty training during those three days.

A Week Before 3-Day Potty Training

We Tried On Undies

About a week before we started the official potty training, I made Theo put on a pair of big boy underwear.


I’m telling you, he does NOT like change. This made me a bit nervous about potty training, but he was starting a new preschool in January and had to be potty trained, so we had no choice and had to start potty training.

Plus, I did feel like he was ready. If he was a young 2 and had that reaction, I might have held off.

Here is my favorite underwear for toddler girls!

I Let Him Pee On The Floor

You probably won’t read about this in any potty training books, but I let him pee on the floor.

He got home from preschool and I put on the T.V. for him and pumped him full of juice.

The floors in our family room were laminate and I removed the throw rug and all pillows and blankets.

I sat him naked on the potty, gave him his juice and let him chill. I didn’t say ANYTHING about peeing in the potty or what we were doing.

He eventually stood up and wandered around the room and ended up peeing.

I stayed positive and calm and had him help me clean it up and told him that soon he was going to wear big boy undies and would pee in the potty instead of his diaper.

I wanted him to realize what would happen if he didn’t have a diaper on before we actually started potty training.

We Read Books About the Potty

We had been reading books about the potty for awhile, but the week leading up to potty training, we read books every day about potty training.

You can click below for some of my favorite books for children on potty training!

How to Potty Train in 3 Days: The Weekend

This is a must-read before you start: mentally prepare yourself for potty training.

3-Day Potty Training: Day 1

Get Them Naked

We went out early that morning to get our Christmas Tree.

When we got home, I got Theo naked from the waist down.

I explained that we were done with diapers and we were going to teach him how to use the potty and as a reward, he would get m&ms and stickers for going pee and poop on the potty.

Keep Them Hydrated

We are usually a water and (almond) milk only family, so when my kids get juice, they are really excited and chug it.

I kept him hydrated with as much juice as he wanted!

Put Them Someplace Where Accidents Can Happen

Do notttt put them in a carpeted room if you can help it.

We put Theo and his potty in the family room with laminate floors. I put the potty training potty there instead of the bathroom because I wanted it to be close so he could get there fast.

I also wanted him to be able to continue watching his T.V. show or movie while he was peeing.

They definitely need to learn to stop what they are doing and use the potty, but I personally thought that was a bit much for day 1.

Do NOT Leave Them Alone At All

Do NOT leave them alone for even a few minutes!

It’s SO important that if they start to have an accident you intercept and move them to the potty so they realize what they are supposed to do.

Every 15-20 minutes, tell them (do not ask, tell!) it’s time to sit on the potty and try to pee.

About 30 minutes into day 1, Theo started jumping up and down and crying that he had to go pee and didn’t want to pee on the floor. I realize at this point, that this is not normal. Most children don’t realize this quickly into the potty training process that they actually have to go pee.

Theo is a highly sensitive child and so I think he is just extremely aware of what’s going on with his body.

I was incredibly positive and shouted happy things such as “You’re going to get m&ms for peeing in the potty like a big boy! You’re doing such a good job! Way to go, Theo!”

I helped him over to the potty, and he peed right into it!

This trend continued all day and we didn’t have one single accident. I was ecstatic and I know this is NOT the norm.

We have also had plenty of issues down the road with pooping, so it wasn’t all a walk in the park.


I went back and forth about whether or not I wanted to reward Theo for using the potty.

It’s a natural thing that children need to learn how to do, and doesn’t necessarily require a reward.

I didn’t want him going off to college and still expecting an m&m for using the bathroom!

I’m kidding, but you get the point.

I decided to use rewards because I knew this was something that would be scary for Theo. I also knew I wanted it to work fast because I had 1.5-year-old twins that I had to worry about as well.

So why not use rewards as a tool to make potty training easy and fun, and take them away when I felt they were no longer needed.

What About Naptime and Overnight?

When I first started out potty training, my plan was to still use diapers for naps and overnight.

I had read somewhere that can be confusing to expect your child to be potty trained during the day and wear a diaper for sleeping, but I was honestly too scared to try it.

At naptime on day 1, it just felt weird to me to tell him he was supposed to be peeing in the potty and then put a diaper on him.

It felt confusing to explain that to him, so when he got up from his nap, I decided that was going to be the last diaper we used.

At bedtime, I told him that he was done with diapers for sleeping as well and to just yell for mommy and daddy if he had to pee.

He was still in his crib at this point. My husband and I woke him up right before we went to bed to pee, and he went, and then stayed dry for the rest of the night!

I was in shock.

I thought for sure I would find him soaked in pee in the morning, but he was dry!

3-Day Potty Training: Day 2

Day 2 went pretty much the same as day 1, except we put underwear on Theo.

If there had been a lot of accidents on day 1, I would have kept him naked for most of day 2 as well.

We did have a few accidents on day 2, but I remained positive and told him he would get it next time. I also had him help me clean it up.

I tried to catch him in the act with accidents and rush him over to the potty so he would realize what was happening as he was doing it.

If your child is struggling on day 2 or 3, then I suggest you look into the Oh Crap potty training method.

3-Day Potty Training: Day 3

Successfully toilet trained and out of the house like a big boy!

On the 3rd day, Theo was fully clothed and we moved the potty into the bathroom!

What About Pooping?

Pooping can take a while to master and there are several things you can do about it.

This post has great tips on how to get over the fear of pooping on the potty.

Poop issues can continue on into older children as well as potty training aged children.

Theo is now 4.5 and we recently struggled with severe constipation that ended in encopresis. If you’re struggling with poop with an older child (at least 4 and up), that post is a must-read!

We ended up with pretty severe constipation and encopresis issues about a year later.

Would we have had these issues with another potty training method?

Our pediatrician said that the problems are not a result of a potty training method or anything that we did.

Is the 3-Day Potty Training Method Right For You?

Only you can be the judge of that! I think it worked for us because Theo is so apprehensive to change and needed a method that didn’t allow for us to falter.

I also think that it worked so quickly for him because he is a highly sensitive child and so really noticed the feeling of not wearing underwear.

It was easier to explain that underwear was our new normal. If your child has a very type A, black and white personality, then it is probably a great choice for them! So there you have it: how to potty train in 3 days! If it worked for you, I’d love to hear about your experience!

Another thing to keep in mind is that it is crucial to use a potty chair for your little one when using the three day potty method. It isn’t practical to try to run them to the bathroom every time they have to pee, so a potty chair that can be in the same room as them as crucial.

Any advice for transitioning from naked to underwear. This is where I am struggling with my son. If he is in the house naked he does perfectly. Always says when he has to go or even just goes himself. He seems very self aware about it(we did not specifically follow this method, he actually just started asking to go potty at least once a day successfully on his own) after seeing that he seemed to understand what it felt like and was pretty motivated we went all in. The trouble is as soon as he is wearing bottoms of any sort he is very inconsistent about telling us he needs the potty. He does it but when it is a bit too late. Some days we wear underwear with no accidents all day and others we use at least 3 pairs. I want him to feel confident about it, so ended up putting training pants on him when we drop his sister off at school(he often falls asleep and misses his chance to go upon getting up because we are already waiting in the car line to pick her up from half day kindergarten. Thanks to Covid going in is not an option).

Wish it would’ve worked for me. I’ve tried everything in the book, including variations of the 3-day potty training boot camp and none of it worked. My guy will be 4 in two months. Feels like I’ve failed because I’ve tried every method you can think of. Not pressuring or forcing either. All positive reinforcement and jelly beans for rewards as well as a hot wheels after going 7 times. I guess I’m saying I’m glad for you and I wish it would work for me. I feel like a failure reading all these articles and how it seems to help everyone else. :(

Gweneth... I so feel you. Potty training our twins took FOREVER. You have NOT failed. All children are different. I'm currently writing a post about all our failed attempts at potty training our twins, and what FINALLY worked, but it might not be finished for a few more weeks. In the meantime, I highly recommend you read the book "Oh Crap." It really helped us to finally get our girls on track!
