R.S.
I gave my daughter soy formula until 9 months. I found out she was alergic to milk accidentally, after I stopped breastfeeding at 7 months, and bought some soy formula. Then at 10 months I slowly introduced milk formula back and she is doing great, no spitting up and problems. I have also introduced whole milk once a day. If your baby is getting enough nutrition from other foods, you can even introduce whole milk. Whole milk is recommended after one year only because it does not have other nutrients than calcium and vit D. I would say try Next Step formula, but I don't like all the corn syrup in the formula, and if your daughter is getting enough nutrients from solids, try even whole milk.
