NO GROWTH

My son is 6 years and 4 month. His height is 107 cms and weight is 14.9 kgs only.
When born he was most healthy baby with 3.75 kgs weight.
But now there is VERY slow growth and he look very weak.
We are very much worried and need your suggestions / opinion / advise.
Please help us.

Both his weight and height are below the 5th percentile for his age which indicates he is underweight. You did not state his appetite. Based on his weight / age, he should be consuming approximately 1800 calories per day for him to grow as recommended the following; Fruits = 1.5 cups; Vegetables 2.5 cups; Grains (cereals, breads) = 6oz equivalents; Meat & beans = 5oz equivalents; Dairy products (milk, yogurt) = 3 cups; Oils = 5 tsp; Additional calories to be used discretionary = 195. This food needs to be divided up between 3 meals and snacks between meals daily. Suggest replacing his milk, at meals and snacks, with Pediasure, milkshakes (milk and ice cream blended), or yogurt smoothies (yogurt, ice cream, or frozen fruit-if he accepts it- blended) for additional calories and protein for weight gain. Hoped this helped.
