Monitoring a child's growth
Avoid sugary juice and instead let the child increase their milk intake. Most times children are over fed on over sweet juice which just kills their appetite to eat food.
And if your child is severely underweight you may have to feed them on a special rich protein diet to help them catch up with weight gain more easily. Do not neglect your child’s growth. A child who is growing well, has proper weight, and is feed on the right foods is set for a much happier future than a child who is underweight, frequently falls sick and is not emotionally resilient.
