I.A.
Not at all. I have 2 girls, 10 yrs. old and 8 yrs. old, as well as 1 boy, 2 yrs. old. My first daughter has her preschool picture (at 4 yrs old) with no front teeth. I worried at first and took her to the dentist. The dentist reassured me, teeth do not know what age they are. They only know when to come out. My other daughter had lost both front teeth by Kindergarden (5yrs old). Hopefully, that helps.
