What is/was the size of your daughter at 14wks old? May daughter is almost 15lbs. I feed on demand and I know she isn't starving but she acts like it and screams when she's done with a 4 oz bottle. I can't keep up with her eating habits while pumping. On the weekends I nurse her literally all day. I don't want her to get so attached to food that she's going to have an eating problem when she's older. Advise?
