We are in the midst of potty training and the overnight pull-ups are heaven sent! They definitely can hold lots of liquid, and the designs are fun for my little Disney Junior lover. It would be fun if they changed up some of the designs, but hopefully we won't be in these for too long. Definitely love the mega pack as it is the best deal. Recommend buying at Target, because they often have a cartwheel deal that applies to the pull-ups as well as using the RED card 5% discount.
