My dd is a little over 11 months old and the last couple of weeks she is crying all the time. She is only drinking about 30 ounces of formula a day. No baby food. I don't know if she is hungry or just crying. She is even only taking a nap for an hour then wakes up crying which is unusal for her. She is waking up in the night for a bottle. Should she be eating more if so how can I tell. I plan on weaning her off the formula soon but I don't know where to start. Yes this is my first baby please help.
