I've got an Eenie, a Bright Bots, a Kmart brand, and some others. I had my first poo incident with the Eenie and it didn't hold that great...eek! Held most of it, it just had some gaps, obviously! I love the Bright Bots one - it's starting to perish, and it's a size 000 - perfect snug fit. I can't imagine getting a size 1 one, because that would be too loose?
