Thank you for your query.
I can understand your dilemma. It is best to have a psychologicall assessment done to know the exact problem with your daughter. With a few sittings with a child psychologist
you may be guided best to deal with the various situations.
Regarding meals, if the child likes food from outside rather than home made then an introspection needs to be done. This situation arises when the family members encourage such food. One needs to be firm and stop outside food and reward the child for taking home made food. It has to be done patiently and consistently.
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
