weight increase

My year n a half old daughter has not gained weight since the last 6 months. We  regularly visit paediatricians who have prescribed appetizers and multivitamins for her ( she is a very poor eater ) . The medicatione  have been sincerly administered and a eating routines have also been followed. No force feeding is done and she is allowed to play n xplore her food. She doesn't like  (does not allow ) to be fed by anyone else and prefers to eat with her own hands.Her deworming is also done periodically. Yet no weight increase n interest in food is shown by her.

Is she drinking milk? Suggest giving her nutrient dense drinks in place of milk for all meals and snacks, such as Pediasure or milkshakes (milk, and ice cream blended) for additional calories and protein for weight gain.
