I know this is a pretty common problem and the second time I'm going through this with now my 2nd child. My ds has taken to undressing, mostly at bedtime, before he goes to sleep. It becomes a great pain literally as I hunch over the crib to re-dress him again. At first it was just his pjs, now its his diaper as well and I'm just waiting until he pees one night and then I have to change the whole bed. It doesn't seem to matter what I put him in, sleepers, 2 piece pjs. I've tried putting a safety pin through the zipper of his sleepers a 1/4 of the way up so you can just slide them on but it makes it difficult for him to get off,(he still managed it). Tonight I've got him in a two piece but took two baby safety pins and and pinned tops and bottoms together. I have no doubt he'll get out of that.
In my mind it would make so much sense for children's clothing manufactures to make sleepers for toddlers that zip up in the back. I've seen them for infants.
Any suggestions? Anyone know of any companies that make such a sleeper?
