Burping every 2 ounces was key for us

I breastfeed and supplement with formula once a day. I notice a change in my daughter bowel movements and gas then she started throwing up so I switch to gerber soy. No more problems

try similac sensative, stop half way through the bottle and burp the baby(sometimes it may take a little bit) and then burp when their finished. may have acid reflux and if they drink all of it when they burp it may come up. my son had to be burped. my son also had formula issues and hes been on similac sensative since 1 month and he'll be one in 15 days.

My baby is the same so we are just trying different formulas
