A. hi dear Tips to help your child gain weight include more starchy carbohydrates such as potatoes, bread or rice in meals. increase their calorie intake with healthy fats – add grated cheese to meals and make porridge with milk. give them high-calorie drinks in between meals, such as milkshakes or smoothies.
