...of my SO. It's bad enough I'm a FTM going through the struggles of breastfeeding. My LO is 3 weeks old and cluster feeds. He's been doing so for 2 weeks. He gets gas pain, he rarely will burp, spits up a lot, and he acts tense and fussy sometimes while feeding. My SO keeps saying he must have a disorder where he doesn't know when he's full and that I need to bring it up to thw doctor. Well I had before and she says he is going through a growth spurt. My SO keeps insisting something is wrong. I'm getting so frustrated. When I ask him what this disorder is called he says he doesn't know but someone told him about it. I'm getting so sick of him being told shit from coworkers and friends of bizarre things/occurrences and believing it to be the case.

Please someone give me peace of mind. Is this normal behavior for a baby in his age range? At night he is fine. Will sleep 3-4 hours between feeding. Its just during the day that he'll get very fussy, spit up a lot and eat almost constantly.
