Here's the situation.  My dd will be 4 in June and has never come out of her room on her own once we put her to bed for a nap or bedtime.  She will just sit in her room and play until we come get her once she wakes up.  Or she will call for me or my hubby too.  But she has never opened her door to come out and we always liked that because we haven't had to be worried about her wandering the house at night.  We are thinking that she is getting old enough that she should start learning appropriate times to come out by herself. 

We just converted my son's crib to a toddler bed and he has been doing good but he comes out when he is done sleeping.  He is 2.  My daughter hasn't noticed yet that he is doing this by himself yet but I know she will soon and I want to help her know what times she can leave her room and when she can't without confusing her.

How have you other moms dealt with this?  How do I explain to her (and my son) that sometimes it's a good thing and sometimes it's naughty?
