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's 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.
