My baby is 2.5 months and is eating very little. I do both breastfeed and bottlefeed. I know I don't have much milk, and I only nurse every other meal. During bottle feeding, he only takes 1.5-2oz each time, and no matter how much we push, there's no use. He used to take the bottle very willingly. He has had bottle since first day born, so is it possible that he just suddenly decides to refuse the bottle/formula. He nurses fine, and the fact that I know I don't have much milk worries me that he's not having enough.
