My one month old baby is teething. is it normal?

A. Are you sure because that normally does not happen before completing the age of three months in a very rare case it can start happening by the time of 2 to 2 1/2 months but if it is happening that early with your child it’s normal I would not say it’s abnormal but it’s actually beyond expectation so you should start using nipple shield when you are feeding the child otherwise the child will start biting you terribly
