Since she was born my LO has not spit up much. Of course she has spit up now and then but it was never a lot and not very often. Well on Wednesday evening, not long before bedtime, she vomited all over my husband. I was at work so I didn't see it but he said that she had drank 8oz of formula about a half hour before and it seemed like she threw up all of that. Apparently they were both covered in it. Then tonight she did the same thing to me. She drank a 6oz bottle and I was rocking her to sleep and out of nowhere she puked all over. There was so much! I didn't even know that much vomit was possible and it was coming out of her nose even. She has no other symptoms going on and seems perfectly fine before she throws up and fine after too. Any idea what could be causing this?
