Years vs Months

Is it just me, or do you get annoyed when you ask someone "oh, how old is your child" and they'll say "s/he's 38 months!" ........ So they're 3. 😂 I just never understood doing that if the child is over 1 or two years old. Maybe someone else's sees the importance of doing that, but I don't.
