first suggestion is dr harvey karp's "happiest baby on the block", it offers real encouragement for the first three months, or the "fourth trimester" as he calls it.
your daughter isn't going to eat more than she needs. it's a natural function; at her age she can't understand overeating. if she drinks too much, she'll spit up. my son is almost two now, and he went through spurts where he would eat upon no end, and others when he refused to eat. i've always related it to his growth spurts, which are a very real thing. he ate the same way when he was her age, but he was a big baby and is a big kid. i wouldn't worry so much about her appetite, rather more her lack of appetite should it arise and last for a while. i know it's silly to reference, but worry about it more when she gets older, some older children use it as a comforting habit, like those kids on maury (yes, i've turned on muary before). they're usually subjected to some kind of trauma and that is how they react, because food is always reliable and won't ever deny them love. i don't think you'll have that problem! let her eat, love her, and watch her grow healthy and strong :)
