Let's say you go to the mall.
Your kid poops.
Okay, now you have a poopie diaper, right? What are you going to do with it?
If you have a wet bag, you pop the poopie in the wetbag and keep it in your diaper bag till you get home
I also have a small one to hold wet wipes
And 2 BIG ones that I rotate using for my diaper pail
