No left face movement on deliberate smile
My 2 year old can smile symmetrically when laughing or spontaneously smiling, but whenever she tries to give a deliberate smile, the left side of her face doesn't move at all. She says her face doesnt feel funny, she's not drooling or acting any differently, she denies headache, and her eyes close properly. It has been going on for at least several months with no change. Should i be worried?
