My growth progress at 14 months

My weight at 1 year and 2 months old is as weight as a bag of 10kg rice. So you can feel the gravity by caring a bag of 10kg rice instead of caring me. But Mummy said I should be more heavier....mb I need to drink more milk which I often did not finish. Always left 1 to 2 oz for Mummy. Sometime even half of it (currently I am taking 5 scoop of milk power with 6 oz of water at nite and early in the morning and 4 scoop and 5oz water at the morning and afternoon).
