i) Calcium – Milk is a rich source of calcium which helps in the formation and building of strong bones. Calcium is important for blood coagulation, energy yielding metabolism, regulation of cell division and differentiation, muscle, nerve and digestive functions. A 200 ml glass of milk provides your toddler about 40% of his or her calcium requirement per day.

ii) Phosphorus – Milk is the main source of phosphorus in your toddler’s diet. Phosphorus plays a vital role in the maintenance of healthy bones and teeth. It plays a significant role in cell membrane structure and regulation of your child’s basal metabolic rate (BMR).

iii) Potassium – Milk is a good source of potassium. Potassium is essential to maintain blood pressure and helps maintain muscular and neurological function.

iv) Iodine – Milk is also a good source of the mineral iodine. Iodine is required for the production of thyroid hormones, energy metabolism and maintenance of healthy skin.

What is the quantity to be consumed according to age?

The Indian Council of Medical Research (2010) recommends a daily calcium intake of 600 mg/day for children aged 1 to 9 years and 800 mg/day for children aged 10 to 17 years. It also recommends feeding 100 ml (standard portion size) of milk and milk products as 5 portions per day for children aged 1 to 18 years, as part of their balanced diet. 100 ml of cow milk contains 118 mg of calcium; and 100 g of paneer contains 476 mg of calcium. Thus, to meet the recommended calcium intake of 600 mg/day, you can feed your toddler a 100 ml of milk thrice a day (118x3 = 354 mg/d). The rest of the requirement can be met by feeding her with other dairy products such as curds, yoghurts, paneer, cheese or other calcium-rich sources such as green leafy vegetables, fish, nuts and oil seeds.

Do girls need more milk than boys?

The Indian Council of Medical Research does not recommend a difference in the requirement of calcium or the daily number of portions of milk and milk product consumption among children aged 1 to 9 years. However, the calcium requirements increase as they grow, due to the growth spurt occurring during the phase of adolescence.

Should toddlers consume more milk?

Toddlerhood makes your child go through an intense phase of developmental changes in his physical, psychological and social attributes, demanding more calcium and vitamin requirements. As milk forms a major part of a toddler’s diet, it serves as the primary source of all the nutrients that your child requires. Picky eaters may struggle to get enough protein and calories in their diets. Milk is an easy, nutrient-rich way to compensate the need and prevent malnutrition.

Best time to drink milk

There is no scientific evidence supporting the taboo that milk consumption should be avoided on an empty stomach. Milk, being a complex food, can be had any time of the day.

Milk is a wholesome food for your toddler. Only pasteurised or boiled milk should be fed to your child to ensure protection from contamination and pathogens. 

On the negative side, some children are allergic to milk proteins or intolerant to milk sugar (lactose). If your child cannot tolerate milk, you may replace cow's milk by an equal volume of curd/yogurt/soymilk/almond milk.

Now that you know the benefits of milk for your kids, ensure they have their daily dose of calcium!
