do not worry she will improve
You should not worry as she seems to be relieved of her symptoms only the voice is changed.
the voice shall improve within few days.
She has no fever
, she is eating normally and sleeping well, then You should not worry.
The only thing to be taken care of is reflux. ie the reflux of food in throat from stomach, which is common in children.
If this reflux is taken care of then the throat will heal faster.And voice will improve.
Reflux is common in children but we do not notice as children do not complaint as they do not understand.
reflux is further more common in children who snore because of adenoid
enlargement. Give your child proper diet and do not over feed her, small and multiple feeds are better. Protect from cold
