My question is that when my son turns 11 months, I want to switch him over to milk. I just recently found that Fairlife has a good amount nutritional value. The only thing is, that brand is lactose free. Can I give my son this milk and still give him regular dairy products (like whole milk cheese etc [those with lactose])? Or will it turn this tummy upside down? Or should I just do 2% or whole milk?
