meri beti abhi 5saal ki hogi but uska weight 15 kg hai to kya ye weight sahi hai ya nahi plz advice me

A. By the time of five year child should be around 18 kg so for a four year old child also this is little less so right now I can only advise you to give more of proteins to the child both veg and non-veg are going to be important and give good amount of dairy products and healthy fats like Desi and butter to your child
