Gaves, I bet there is nothing wrong with your milk, try not to worry about it. I've got a tiny baby too. We'll know his weight for sure tomorrow at his doctor appointment, but I'm sure he's not much heavier than your girl. And that's with breastmilk on demand + 12oz of formula!
Bumpin, Arthur is the same right now. He loves papa, and if papa's there mama is invisible. He cries everytime OH is going outside... OH being a smoker, you can see the problem there.
