I have a call into the pediatrician but I'm wondering if anyone else has had this issue. My son is almost 9 months and has been randomly spitting up/throwing up some of his bottles lately (he's FF). He's always had spit up problems but this is more like 1/2 of the bottle to almost the whole thing. This happened a few times last week and I attributed it to the fact that he was crawling & sitting up too soon after he ate. Right when we had thought about calling the doctor it stopped but now the same thing is happening again. I'm 99% sure it's not any kind of stomach flu because he's perfectly fine otherwise- no fever or fussiness or any other sick symptoms. Is this some phase that they go through?
