My son's three favorite cartoons are Little Einsteins, Dinotrux, and... Wait for it... My Little Pony! He's 2 years old.
I swear I didn't brainwash him. He'd just sit with us when me and hubby were binging on mlp. I'm teaching him the names of the main six. Fluttershy was first when he got her happy meal toy. Then it was Pinkie Pie and Applejack. He's having trouble saying Rainbow Dash. Haven't bothered with Rarity and Twilight yet.
