Luvs pulls up are the best
Size: 5T-6T, Unit Count: 48
I love this brand. It’s very secure, and the adjustable band makes it easy to tighten without taking off my child’s pants. It doesn’t leave an odor, the texture is smooth, and my child is always comfortable. The price matches the quality, and there’s no leakage or spillover. Overall, it’s very durable. Make sure to have it correctly fastened because the Velcro can leave scratches on child skin.

Toddler approved
Size: 4T-5T, Unit Count: 99
Fits true to size and easy to pull up and down by my toddler. Very absorbent - perhaps a little too absorbent as it's taking my daughter forever to be potty trained and she's content in her soiled training pants... Great quality overall.

They prevent leaks, and fit great!
We have always used Huggies diapers for our babies and young toddlers because they were the only ones that never leaked or caused a rash. My second daughter was fully potty trained at 2.5 years old and never needed pull-ups. However, our third daughter, who also trained at 2.5 years old, digressed with her nighttime potty training due to instability - we moved twice within the first 6 weeks after she potty trained. So we had to get pull-ups for her to wear at night. Obviously since we loved Huggies diapers, we tried Huggies Pull-Ups, and again, they did not disappoint! They never leak, even on nights when she doesn't get up to go at all, and has lots of pee, and they have never caused a rash either, no matter how full. She's been using them for 1.5 years, at night, and we have never had any issues. They are dependable: decently comfortable to the child, do not cause rashes, fit properly with the ability to adjust at the thigh (if needed), and they prevent leaks! I highly recommend them!

Great fit and makes potty training easier
Size: 3T-4T, Unit Count: 84
These training pants have been a big help during potty training. They fit comfortably and feel soft against the skin, more like real underwear than a diaper. The stretchy sides make them easy for little ones to pull up and down on their own, which really helps with independence.
They do a good job holding small accidents without leaking, and the fun character designs make my little one more excited to wear them. The pack comes with plenty to last through the training phase, which is nice when you’re going through a few each day.
Tip: keep a few extras in the car or diaper bag for outings. It makes potty training on the go so much easier.
