I struggle to Feed my 2 Year Old

Maraming times na ayaw nya kumain ng rice. Mas gusto nya nalang palagi naglalaro. He's hyperactive but only takes 17 to 19 ounces of milk each day. He takes his vitamins normally naman. He's healthy kahit hindi sya palakain. Now, my questions are, okay lang ba if puro milk, breads and fruits lang ang kinakain nya the whole day kahit walang rice? Is it normal? And, if ever, pano ko pa kaya pwedeng iimprove ung appetite nya para kumain sya ng madami by not using vitamins since natry ko na lahat ng pampaganang vits and nothing worked. Thank you po sa sasagot! 🙏
