Hello doctor. My baby is 7.5 month old. Since 10 days she woke up crying in every one or two hours scratching her ear from inside and Pulling her hairs. The case has become severe in last 2-3 days and now even at day time she is been waking up quite often crying and scratching her ear and pulling her hairs. As soon as I pick her up she sleeps. Is this the sign of teething? If yes, how long will it last???
