For the past couple weeks, my 19 month old daughter has started a pattern of throwing her teddy bear out of the crib multiple times at bedtime. She is quite attached to her bear and is not able to fall asleep without it. Once she throws him out she repeatedly yells "uh oh" until we come and give him back to her. We put him back in the crib and she immediately lays down as if she's ready to sleep. We limit interaction by only saying "night night" and leaving the room immediately. Sometimes she only does it once, others up to 5 or 6 times. Any suggestions on how to deal with this?
