Since a recent visit from Grammie and a new box of puzzles Griffin has become a puzzle man. He has worked his puzzles and is now doing Sydney's old puzzles. He is putting 35 piece puzzles together without any help. He likes to sit on top of the sit and spin and he is very patient. I love that he loves puzzles and I do believe he will be getting a few new ones for Christmas. Our favorite brand is Ravensburger.
