Did your newbie go through a growth spurt around 10 days? Our nurse told us to expect this and that he would be super hungry. The past few feedings he has fed until full but won't settle down and sleep after like he normally does. The past 2 or 3 times I've fed him again about an hour later (usually go about 2.5 in between feedings) and he will finally settle down and rest. he's 9 days old - does this sound like a growth spurt?

How long do they usually last and after they are over did your LO go back to longer stretches between feedings?
