My son tends to do that too. It's like jeez thanks. I was at a benefit the other day and when we first got there I had to feed him and when he was done he puked all over me, I'm like thank you so much! Need to start packing an extra change of clothes for me in his diaper bag lol

My daughter does that after EVERY feeding. I've been dealing with it for 8 weeks now

That's what babies do. Probably reflux or ate more than his little stomach could hold.

He might be getting too much. That's what my son used to do. It would be like all his breastmilk or formula.
