My son is now 4 weeks old. At around 2 weeks, he started spitting up A LOT (like 3-4 times after each feeding), then he would become fussy and inconsolable (like he was in pain). I suspected a few things (like reflux) but his pediatrician blew me off like I was an overly paranoid ftm. I have since changed a few things and they seem to be helping. First, I have cut dairy from my diet. Second, I have started feeding him more frequently (around every 2 hours instead of around every 3 hours like before), but I am only offering one side to limit the amount he gets at each feeding (the spitting up seemed worse when he ate a lot). And last, I keep him upright for about 30 minutes after each feeding. Like I said, these changes seem to be helping a bit with his spitting up and fussiness.
Now I am concerned that he is not getting enough to eat, though. He still has lots of wet/dirty diapers every day, but I feel like now he wants to eat close to every 1 hour instead of every 2 hours. Could it be a growth spurt? He's now 4.5 weeks old, and this has been going on for a week - I thought growth spurts were at like 3 weeks and only lasted a few days. Also, if there are any other moms out there that have dealt with reflux or dairy intollerance issues and have any other suggestions for me, I would appreciate the advice. Thanks!
