i did look at the abc one when i bought my mb, but something about it just didn't look right. i love the way the kids sit next to each other and interact with each other in the mb. my ds and my friend's dd were holding hands and sharing a packet of rice snacks in it the other day- so cute!
pap- the bumper bar is like a sort of roll bar that goes across where they sit and they can sit up and hang on to it. ds loves it!
