M.H.
My daughter also did this a little bit before she turned 2. She had slept through the night since I brought her home from the hospital but all of a sudden every night she was fighting sleep and it drove me crazy! I did let her sleep in my bed for about a week and after that I put her back in her crib. She still had a problem falling asleep for a little bit, but I think she learned that I wasn't going to do anything about it and she finally went back to her normal way of going right to bed. I definitely think it's just a phase, they're exploring and they would rather be doing that than sleeping. They don't want to miss anything! Hope this helps and good luck!
