Spitting up

Alison

My daughter is 9 days old and not every time but several times since yesterday she’s been spitting up a lot, like what looks like at least half of what she ate. Sometimes it’s projectile and others not. She’s got a slow flow nipple and I stop to burp her about halfway through the bottle but it doesn’t seem to be helping. Breast milk not formula btw. I’m starting to worry a little, any tips or tricks?
