Sometimes, my LO vomits after I give her the supplement. But I am wondering if it's how I'm doing it and when. I always give it at bedtime and then I nurse her to sleep. And then sometimes, she vomits all over the place. She did eat alot of cheerios tonight at church and then came home and nursed. She was never a big spitter upper. She is 13 months old. It is just the enfamil supplement. Is there a better one that easier on her tummy? Or should I give it on an empty stomach? Or with food, rather than breastmilk. She barely eats any food, anyway, That's how we got ourselves in this situation to begin with.
