Why does my daughter have so many teeth

Mr

My daughter got her first tooth at 4 months and it's been non-stop ever since. She's barely about to be 14 months in a week and she has 12 teeth. 12!!!!! She gets so cranky during teething periods (which feels nonstop at this point) and I can only give her baby Tylenol because she's too little for teething gel 😵
