My 9 years old boy is underweight .. he lives an active lifestyle (he goes for regular Soccer training in school) n I believe he must have enough calories to sustain. Though I Ensure he has balanced 3 meals , drink 1-2 glasses of milk daily n snacks in between meal but he is still not putting much weight fast enough. Chance upon this weight gain milk powder for kids n am tempted to let him try. Anybody has tried this on your kids n has any reviews for me ? Thank u!
