my baby is 4 months old. I have been observing her voice have changed as of she has suffered a throat infection or once I had given her grapes in a fruit nibbler. please help me to get her Back with her normal voice.

A. grapes are sometimes sour that's why she has throat irritation. it's good to avoid fruit nibblers, and offering anything before 6 month of age give steam inhalation, increase breast feeding. it's preferable to visit your doctor, for further evaluation and exact treatment or management.
