Hi, she's in her crib (she's 9.5 mo) and it's been fine until now. But the thing is, the crib's a little bit broken. So now that's she's more mobile, it's not that safe anymore. We have a twin bed for her already. I read that she can use a bed when she's 35 inches tall, but now she's only 29 inches tall. But I really want to move her out of that damn crib asap. Does anyone use the Gro company's zipped in sheet set for a baby with any success? (It has a fitted sheet, duvet cover and pillow case that all zip together to prevent falling out of bed). Thanks!
