I just tried weaving the bumpers through the rails. Looks like it should work.

We're using the breathable mesh bumper and then will put the real bumper on when she gets more mobile. We did the same thing with my 3 year old and it worked great!

No macey doesn't. But I have her in a sleep sack. (Armless one) and she is usually cuddling her blanket she likes to hold it in her hands.

Do your babies try to get their hands/legs through the sides?

We have a pink breathable mess crib liner. A lot from target.
