my 12 week DS is having the same problems now. He shows no signs of hunger after waking up from his naps. So I had to take him to a dark room to avoid all the distractions to get him to eat every 3 hrs. Sometimes, he refuses and eat after 3.5 hrs. And each time, it takes almost 1 hr to feed just 4oz. I BF or sometimes bottle feed him with EBM.
During the day he eats between 3-4oz., but for the feed before bedtime (last feed around 5:00 and bedtime around 6:30), he is super hungry and would eat close to 8oz. for the past couple of days!
Don't know why. Is this due to a growth spurt or is it because he is going to have his teeth soon? Our doc told us our LO will have his teeth soon.
