My poor baby just projectile vomited 4oz of her bottle! 😩😢 it's not the first time she's done it. It only happens every so often but when it does. It's not just spit up, she aftually throws up and it comes out her nose and she can't catch her breath and it scares the hell out of me. Any of you have any idea what's going on. She's almost 5 months. I was thinking acid reflux??
