The other day I heard Joseph over the monitor after he woke up from his nap. So I went in to get him, and this is what I found:
The mattress is already in the lowest position! Nine months olds are not supposed to outgrow their cribs!!!
So we removed the bumpers and aquarium and everything else he could launch himself out on, and we're getting a "crib tent" from a friend to trap him in. What else can we do???
