We moved LO (2.5) to a toddler bed 2 weeks ago. She was excited about her big girl bed and was fine for a week. And then started getting out. For a few days she just played in her room, so I let her be and she eventually settled as usual, but the last two days she's opening the door, insisting to come to our bed (she's never slept with us). Both nights she didn't settle until 11, exhausted and cranky (as am I). I'm thinking about locking her in but husband is really against it. I don't want to create bad habits like rocking and etc but this can't continue either. Any tips?
