A. Your child is having a very less amount of milk and the gap is huge in this is a child can easily have somewhere around maybe 210ML amount of milk in one go easily and that to every 3 to 4 hours write a child is practically not having anything which is why your child is underweight I do recommend you to see your doctor once
