So my little man turned 2 weeks on Sunday. We had a pretty regular night last night feeding every 2-3hrs. Woke up around 7am and nursed. He usually stays up for a little bit in the morning then nurses again and goes back to sleep. Well today he nursed and nursed and nursed and never went back to sleep. He basically nursed or screamed all day long only falling asleep for a few minutes at a time. As soon as I'd move or he would realize he wasnt nursing anymore hed start screaming uncontrollably. Hes also been really gassy today. Any thoughts? Just a growth spurt?
