My 4 month old is EBF and so far, these diapers have been great for taking a quick dip in my parents' pool. Although my baby has not pooped while wearing these yet, I feel confident that they will hold it all in. I am sure that the snaps will come in handy when my baby inevitably poos while wearing these diapers. The only downside of these is the way it snaps. We cloth diaper except at night so maybe I'm just used to doing it that way, but on the diapers, the wings wrap around to snap onto the back. With a little practice, I'm sure I'll get used to this. The designs are more beautiful in person!
