Talking to sleep

Casey • Second pregnancy with a 3 year old girl already. Surprise pregnancy but happy nonetheless.
Sleep seems to be a huge topic with everyone but does anyone else's baby talk themselves to sleep? My 6 month old has done this for awhile now. It's okay for the initial bedtime but lately she has been waking up before midnight talking/fussing, not crying. Trying not to feed her initially because she shouldn't be hungry. Eating 3 meals a day and 4 bottles albeit no more than 6 ozs. She just won't eat more than 6.
