T is 3 months and ebf- which means thin runny poo. We are going to be at hotels 2 different times this month that have pools and my parents have a pool. I got a great deal on disposable swim diapers at Costco since I knew we would be getting a lot of pool time this summer- but they say they start at 16 lbs- the babe is only 13.

I really want to take her in the pool before she starts solids- but I'm worried nothing will contain the poo. Any experience? Should I just skip it? Double up with a disposable and one of my BG 4.0 shells?

I feel like there are places like the Y and those baby water survival classes that let tiny babes in the pool. I just can't find much online on this subject. Thanks!
