DD was on Alimentum RTF. A few days ago we switched to the powder form. Now she's spitting up a lot more. Anyone have this experience, or any insight to share? I'm wondering if we just need to switch back to the RTF and see if that makes a difference. FWIW, I don't think it's the added corn in the powder form. We have been putting corn syrup in the bottle with both RTF and powder, to help with consitpation that is the result of the added rice cereal due to reflux.
