Okay cool. Well regardless of what I give it to her in, how much should I be giving? Maybe it's common sense to others, but I feel really out of my depth I don't want to give too much, or too little.
There are no silly questions PZ. This is clearly something you're worries and anxious about hun. It will all work out and you will both be ok.
Your little miss won't take too much if she doesn't want it. Let her be your guide. If she wants more than you originally give her she will let you know, if she doesn't want what you give her she won't take it.
