17 month old baby weight 8kg only and her birth weight 2.5 kg i am very stressful

A. Actually the weight should be somewhere around 11 by the time of 18 months so right now your child is quite underweight which is why am going to recommend to give all the family foods plus lots of proteins in the diet you can go for both vegetarian and non-vegetarian and along with it good amount of fats and carbs should also be given
