My 4-wk old has been in a growth spurt for abt 4 days, with more frequent feedings than usual. However, starting last night, he's also wanted to nurse for much longer each time, going from what normally is 15 mins to now up to 30 mins! (and then sometimes followed by a large spit up). If I try to cut him off after say 20 mins, he will start to cry and fuss. Are these longer feedings also normal for growth spurts? I don't think it's a supply issue b/c he is still having lots of wet diapers that are if anything, heavier than before.
Thanks for the insights!!
