my daughter was a preemie and that was an almost every day thing to deal with for me. just reflux. her doctor recommended we add cereal to her formula and it helped a little but really they should grow out of it.

acid reflux then talk to doc to be sure

She's on soy milk tho.

She May Be Lactose Intolerant. I Was Doing That While I Was A Newborn & My Mom Found Out That I Was Lactose Intolerant. Nobody Else In My Family Is.

Sitting up

is she laying down or sitting up

It just randomly come out & if she sneezes it's been coming out.

that happens when my son is over full. maybe she ate too much
