My little guy was born 48 hours ago he latched right away and had been latching at the hospital just fine. We got home last night an ever since he doesn't wanna eat. He's not crying or acting hungry so I've been waking him every 3 hours to try bc I hear him tummy growling but when I put my nipple in his mouth he just sits there like he doesn't want it and then falls asleep. I'm getting worried tho bc he hasn't eatin anything in like 9 hours. Help!
