Hi i am a breastfeeding mother of 5.5 month old baby. After delivery I used to wear cotton in ears and socks, slippers. I used to wear sweater and scarf when I went out. I used to wear sweater sometimes in home. When baby was 3.5 month old there was sound in ears. Doctor said my both eustachian tube is blocked it will be normal after some days. But my mother in law said that it is due not wearing scarf in home. is it true please tell me
