great question. we are taking our three year old to the dentist with us for his first visit next week. The dental centre have said every six months is a good idea from 3 onwards. Baby teeth still need to be cared for, and oral hygiene is a good skill to learn from the get go.
They're pretty young. I've taken them twice, a year apart. They both had their teeth cleaned. My kids are still young, but I think it's important to get them used to going to the dentist and used to looking after their teeth from a young age.
