I would double check that with your Lo's pediatrician. My friend's son was 10 months and was given the OK to start trying cow's milk. He was 24 pounds, eating solids well and was breast feeding 2x a day. They began giving him a bottle of cow's milk before naptime, and increased it to having milk with solids as well. I think it does really depend on the baby and when the doctor gives the OK, cuz everyone has a different opinion.
