Baby vomit help

Cass

So a few days ago baby started having really bad trapped gas being breastfed. We’re transitioning to formula as of yesterday (bf just isn’t gonna work for us long term) and my baby has been projectile vomiting yellow which looks like bile and it’s so much 😭

Anyone go through this? What was the solution or outcome?

I’m so nervous to even lay her down because of her choking on it
