Kids grow up so quickly. Take Fantasia Barrino’s baby boy Dallas Xavier, for example! It feels like just yesterday that the little guy was born but the leading man in Fantasia’s life will turn three this December. You know what that means: Time for a check-up!

The American Idol Season 3 winner and her son headed to the doctor yesterday (March 26) where the two-year-old was set for an appointment, emphasis on the point.

“Big Man had to get shots Yesterday.. Aww Mommy Baby Sad.. I Hate to go with him for those..,” Fantasia captioned a photo of her little guy sitting on the crinkly paper of a doctor's exam chair.

Holding a Thomas the Tank Engine book and rocking nothing but his undies and some socks, Dallas looks so much bigger than last time we saw him, wearing a big ole baseball cap and looking all kinds of adorable! Before we know it, this guy will be taller than both his mom and his big sister Zion (who’s looking plenty grown-up herself these days).

Mama F doesn’t go into details on how the visit went, but we hope Dallas is doing well and maybe even got a lollipop or two out of the trip.
