You would think I know it all by now as this is my second baby. My newborn vomitted last night after feeding. She actually nursed twice.... the second time was more for comfort, but I have lots of milk so the breast always gives her milk. I chalked that time up to getting too much milk due to comfort nursing. But she vomitted again tonight about 10 mins. after a feeding, and I'm wondering if she is just getting too much milk??? She did gain 10oz in 3 days at her weight check!!
