My wee boy is 8 wks old and is part breastfed, part formula fed for this past 4 weeks. We use Aptamil formula for him. He seems to be a hungry baby, eg will take 11 oz formula in one go, he seems happy, wakes once (occasionally twic) for feed at night. So 2 questions: what made you decide to go onto hungry baby milk for your babes? and what is the difference between normal and hungry, as the calories etc on the packet look the same?
