LO is about to be 15 weeks and has been feeding full feeds every 1.5 hours with a small top up feeds 45 minutes later bc he shows hunger signs. I feel like he's been doing this for a week or so. Before it was every 2-2.5. Is this still a growth spurt? He did start sleeping 9-10 hours straight at night a couple of days ago. Is he stocking up on additional calories during the day to sleep through night?
He was also born with a smaller stomach if that contributes to it. Any advice or anyone else experience this?
