Pretty much sitting on his own

As if it is a monther's day present, Robbie started to pretty much sitting on his own. And I first realized it when I try to get him to model for aunt Lisa's knitting thinking I will just prop him in the chair, little did I know he didn't need the help of the cusions. And today at grandpa's for mother's day, robbie decided to sit for a good minute un assisted chewing on one of his toys, too bad, I didn't have my camera in hand.
But I had to show off robbie's handsome sweater and aviator hat from aunt Lisa.
