my LO will be 7 weeks tomorrow and he spits up normally since about 3 or 4 weeks old. but in the last two or three days he has been spitting up what seems like his entire or half of his feed. he is formula fed exclusively since he was a month old. he got supplemented formula since about 1.5 weeks. My milk never really came in. I read about pylori stenosis and it is making me paranoid since he has just randomly started spitting up a ton all at once, both right after or during a feed and an hour or two after as well sometimes. has anyone else had this? I have tried feeding him slower, more breaks to burp, etc. he has been getting 4oz per feeding about every 2 to 3 hours since about 4 weeks old. I am going to try reducing back to 3 oz per feeding and see if it helps.
