I tell parents that I feed on demand. So they must provide enough to feed their baby until they are full. I do not limit them; a baby will stop eating when they are no longer hungry! My brother learned this the hard way with his son, they followed what a book said and wouldnt give their baby anymore then what the book said. So of course they were waking up a million times a night because of a crabby baby
Once they finally stopped listening to all the “experts” ..they got a full nights sleep.
