S.S.
I hear you on the out of bed thing, we just went through that w/dd 2 1/2. The first 3 wks were great she just went to bed but then she started getting out only at nite nap was still fine, it got to the point where she would go to bed @ 8pm & finally go to sleep about 10:30 or 11 extremely overtired and then would be awful the next day. Well we finally said to ourselves maybe she isn't ready for a big bed, all kids are different, so I got the extra crib out of storage put it in her room, she is a much happier child, she goes to sleep right away her behavior has done a 180 in terms of not throwing a tantrum every day all day long...Some kids just aren't ready for the freedom a big bed gives them.
I was worried about stepping backward into the crib again but I think her sanity and mine are more important than the hype that going back to a crib will be psychologically damaging, she's 2 she doesn't even ask to sleep in her big bed even though it is still set up (bunk beds sis has top).
She enjoys playing on it, we will revisit sleeping in it in about 6 mo. but for now she is happy this way.
Good luck to you.
