So long as babies hv no allergies to diary, u can start ard 8-9 mths. All my kids started later as they had lactose intolerance and I dare not try until after 1.5 years. So far after dat, they r eating well and simply love kraft cheese sticks and laughing cow cubes.
Cheeses are good for baby and may be introduced as early as 8 months as long as there are no dairy allergies. You can start by offering milder tasting cheeses like Jack or American cheeses. My friends babies love those kraft cheese sticks.
