My daughter will be three months in a couple of days and has recently started to give me problems while feeding. She is bottle fed and she has been taking the bottle then kind of thrashing her head around and wiggeling when she has the nipple in her mouth. Yesterday I tried the next stage nipple (I use the drop ins and they only have slow, fast, and variable). She did great. Actually finished her bottle and didn't act hungry but now today she acts like the bottle is way to fast. How can she do so well one day and the next it be so hard to feed her again. I'm starting to think that maybe I need to introduce her to solids. Rice or Cereal? What do you Mommies think? I am a first time Mom and I hate to admit that it is frustrating me that it is so hard to feed my sweet little girl. Any advice would be great.
