 [ Symptoms ] my 11 month old has gerd is on special formula when can i try her on non fat or 1  milk [ Disease ] they typical time that babies are switched from formula to milk is around age 12 months so you are a bit early since babies actually need some fat in their diet the change is usually to whole milk not skim or 1 at first with the pediatrician is okay and assuming your child is eating well fromt he table you can make those changes but remember that milk and formula are not equivalent
