Transitioning from Formula

Nicole

So my March baby is a preemie so her doctor told me to wait until she’s closer to her adjusted age of 12 months to start her. So I tried whole milk... she vomited. I tried soy milk..... she vomited. Now I have her on the Similac Toddler formula since she was on Similac Advance and she’s still spitting up. Keep in mind she NEVER spits up. Is it just that her stomach has to get adjusted? It’s been 3 days straight on the toddler formula.
