My son is 13 months old but still he hasn't got his teeth.. is it anything to worry abt..??

A. hi as such no need to worry because teething can range between 6 to 15 months age. but as delay can be caused by calcium deficiency ,I advise to give calcium rich food like ragi , nuts, dry fruits more give sunbath for 20 minutes a day avoid giving RO water maintain good hygiene using Babyhug multipurpose cleaner
