please dont use a regular bumper. i cant believe they still make them. when they talk about a baby suffocating on it, its not only talking about when the baby is tiny and cant back up and gets pressed against it. a lot of suffocation occurs from a baby having their face close to something, not necessarily pressed against it, and they re-breathe their own carbon dioxide as they sleep, therefore not getting sufficient oxygen over a period of time. i have a friend who lost their baby at 6 mos, obviously mobile, using a little blanket that ended up over his face, of course not tightly or anything. i dont know anything about the breathable bumpers. you really dont need them, unless your baby has a head banging issue, he is really not going to hit his head very hard. think about it, how much momentum can he possibly get going in there? i know they are pretty, i bought the fancy set (waste of $$) with my first baby too. used it until i walked into the room to find him sleeping soundly with his face against the bumper just like they say. i had a mini-heart attack and took it right out. *** however, if you do want a solution.. here it is.. the crib tent 2. its ugly, yes. and there is nothing better, imo. getting their arms and legs caught definitely is an issue, the crib tent will prevent it, and will keep his paci or whatever in there too. more importantly, you will be very very happy later if he gets used to it now. i know right now it seems like forever away, but in the blink of an eye he will be standing up in there and hooking that little foot over the edge, and you will be freaking out about letting him fall out vs dealing with putting him into a bed. i would imagine its very hard to get most babies used to the crib tent later on. my 2nd 2 kids used it from the start, they never knew otherwise, and its a lifesaver. after 3 kids i have tried a good amount of the products/gimmicks out there, and i put this in my top 5 easily. one step ahead will have them, though maybe you can get it cheaper on ebay. and its not a bad idea to buy those zip-off sheets, as its a pain to change the sheets with it. i dont have them, i was too cheap, i just take the mattress out and layer my sheets/pads on it and just pull them off as needed, a great tip for the middle of the night mess, by the way. changing the sheets with a bumper is a pain too, so not much difference there. but it is safe, and thats all that matters.
