Projectile vomiting?

Amanda

My baby is 12 days old today she was born on 5/26/2018 and ever since she was about 5 days old she’s been projectile puking about 5 times a day. I had to stop breastfeeding because I thought that was the source of her puking so she’s on formula now. The puking hasn’t stopped so we took her to the er a few night ago and got an ultrasound and a ct scan and they said everything looked fine. I go to her second appointment tomorrow and I think she needs to be on a different formula. Has this happened to anyone else? It’s very scary and makes me not want to fall asleep at night Incas she pukes In her sleep :(
