My dd is cutting her molars. She went from sleeping great to being awful! She wants to be held all night. The minute I pick her up she's fine. Molars or do I need to sleep train again? When we did before it was ten minute cries at most. Not knowing it was teeth at first I did train and she cried a long time. Now I know we have teeth coming but the minute I pick her up she lays head on shoulder and sleeps.
