K.C.
Hi L.! Your son is 20 days younger than my son and shares the exact birthday of my niece! My oldest is now 5 and I started taking him when he turned 4. My youngest (2 in 5 days) will be going for his first time at his brother's next check up so he will be about 27 months. I have a girlfriend who started taking her 5 year old right after his 1st birthday. We go to the same pediatric dentist - I would DEFINITELY recommend a pediatric dentist. Ours told me they like to start seeing babies between 2-3 years old but can start coming as soon as they get their first tooth. Best of luck and happy almost birthday to your precious son!
