Question: my son is 6 days old today and he usually wakes up in the afternoon and likes to be talked to and look at the christmas tree. well this past afternoon he slept thru figured it would be a long night but he has slept amazing. I know its normal for babies to sleep more while going thru a growth spurt so I'm guessing that happening. But is it normal for them to also stop eatong so much. He was up to eating 2 ozs of formula every feeding but for the past twelve hours he has only eat 1 oz evrry feeding is this normal should i be concerned?
