My baby girl is 9 months 15 days old but delayed in teeting... tell me the reason pls

A. No ma’am you are mistaken over here the child is not having any delay I do understand your concern as a parent who must be really worried but a lot of parents do not know that the first teeth usually can be seen between the age of three months to 17 months so if you look at it you left it in enough time and in case of any doubt you can always consult a dentist
