Pros: baby falls asleep in the Beco Butterfly2
Cons: the straps are hard to adjust
I like my beco butterfly 2 . It's stylish, made with organic material,and seems pretty strong.My 5 month old falls asleep in it so that is wonderful for me.
Personally I don't like the straps.. they are hard to adjust while wearing the carrier with my baby in it. I've found the Ergo 's straps easier to adjust and it's faster to put on than the beco.
It was on sale so that was a plus.
