Last night after BFing DS, DH was holding DS & DS all the sudden threw up. It came straight out & all over DH! DS had no fever as his under arm temp was 98.3 & he is not sick at all. So, could this be from OS? Maybe not enough of hind milk & had too much other milk? Few days ago he seemed as if his tummy hurt like he had to poop or had gas or something & was a bit fussy & he burped a few times then spit up & was fine then. After throwing up last night, he burped a little then had hiccups awhile. Both those times I had chocolate & normally I don't b/c of my hypoglycemia. Could it be a reaction to the chocolate? Never had our two other LOs throw up like that so young. He's only 12 days old. Any ideas? Oh, thought might be chocolate also b/c he keeps wanting to nurse but fusses some & pulls on & off my breast at first. Has a face as if tastes is funny. But he also spits up some b/c of OS as well. So, I am confused with him throwing up.
