Yup sounds like growth spurts. You know he is getting enough by weight gain and diapers.
I read that too. I also read that they go through a growth spurt at around 2 weeks. Maybe that's why he's been fussy and been nursing more..
He'll eat til hes full. They tend to go through a lot of growth spurts the first few months. With my first she nursed for 2 hours and 3 hours later she was hungry again. He's just trying to get ur body to produce more for him after his growth spurt.
I'm a ftm but I thought I read somewhere that ur not supposed to get then on a routine that early, and they eat every 2_3 hrs, ur baby has growth spurts so I'm guessing that's why he.ways mire at timrs
