Since my son has been home he acts like a normal newborn baby. He is w weeks old. He eats about every 3 hours. And sleeps pretty much the whole time in between. He poos and pees every time he eats as well. I fed him at about 9pm tonight and usually he wpuld wake up 2 hpurs later hungry, but he slept and 1230 got here and i woke him up and he was acting like he was hungry but i started to feed him and he ate for like 2 mins and was knocked out.refused to even take his bottle and i tried and tried... Eventually i gave up and decided to change his diaper which he hates and usually screams. He slept right through that.... When i was done i picked him up and was just worried and holding him for a second and all hes doing is sleeping.. I layed him down thinking he woulf get upset like he usually does.. Nope... He just sleeps.like i said since about 9pm. Should i be worried? I dont even wanna lay down and sleep because im so concerned.
