Anyone’s else’s baby sick up everything?

She spits up her milk all the time but is still putting on weight etc she’s 7 months.

She keeps solids down well but not her milk. She was breastfed for 3 months then I went to formula.

I’m so so frustrated that I can’t help the spit up, I’ve tried Gaviscon and it made her constipated.

I want to stop the milk but I don’t know if I can match the vitamins in baby milk within foods daily?
