C is almost 5.5 months. Normally, she eats between 25-30oz of formula in a day. The last couple of weeks she has been eating 2-3oz and then refusing to eat any more. She will arch her back, turn her head and get angry and start yelling/crying if we continue to try and get her to eat.

Since 4 months she has been getting one thing of baby food a day. She just eats however much she wants, whether that be 2 bites or the whole 2.5oz container. (I don't want to hear anything about starting solids before 6 months, please. It was a decision made with our ped and we are all comfortable with it.)

Well, today she ate 5oz of baby food. She ate a bottle and about an hour later we did the food. She still seemed hungry after the first jar so I offered her another, thinking she would eat a little and be done... she finished the entire thing. Grand total today, she has eaten about 13oz of formula and 2 containers of baby food, one with a tbsp of rice in it. She will likely eat 1 more bottle of 7-8oz before bed and another 2-3tbsp of rice cereal.

My question, is this normal that they start refusing to eat like this? I feel like she may be trying to wean and I know she is way too young for that. What do I do?
