S.S.
hey B., I never did formula, but from I have learned through my nursing mom's group, soy is one of the best to go with. The fact that she wants to eat less more frequently mimics that of a breastfed baby. The way it has been explained to me is that a breast baby learns when they are full because the milk changes during the feeding. A bottle baby regardless of what is in the bottle learns to "finish" the bottle. Therefore a bottle baby's stomach is slowly being stretched. The soy blend differs from regular formula which is probably why she is taking less more. Also being only a few feeks old, her eating pattern will vary.
