Sophia is a big spitter upper. I call her my little fountain because anytime you look at her there's something flowing out of her mouth. Sometimes it's just milk dribbling, sometimes it's that curdled spit up and every now and then it's full on vomit.
She's totally happy before during and after the episodes so I'm not really worried about it. It's just annoying that her cute outfits always have to be covered by a bib.
I have talked to other moms with spitter uppers and they said she should outgrow it around 8 months or so, around the time they can sit up on their own.
If you got nothing to bring to the table - don't even bother sitting down.
