Thank you for your query.
drops may help in increasing the appetite. However you should not force her to eat. As a parent I can understand your concern but the child will behave in the manner described by you if you force her. No one can remain hungry and let her demand it. Give her meals at the appropriate time and if she does not have it remove the plate. Offer it again after half an hour.
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
