wow !! so feeding your new baby every 2-3 hours and they take 3 -4 oz means they are a hungry baby !
why not add more formula to the bottle and make up a 7 oz feed?
it is really sad, actually. and slightly frightening that parents do not know the absolute basics of feeding their baby.
and what is normal and not normal
i am 35 and eat/drink something every 2 - 3 hours at least !! even if it's just a drink of water or a piece of fruit .. 4 - 6 hours between meals/snacks would be v difficult !
