I have put up a couple of puzzles on the shelf for babydoll since she was like 10 month old. But she would just take out the each puzzle piece and strewn them all over the floor.
Recently, i discovered she can do something new!
She has learnt to put the puzzles into its right places by matching the pictures! I would pick out a piece and ask her 'where do we put this?' or i might say 'where is the pig?' (whichever animal piece i am holding). She would find the matching picture (there's a corresponding picture under each loose piece) and promptly put it in its place. Most of the times, she can't quite fit the puzzle into the slot but at times, by some magical luck she can.
This is another puzzle that she loves. Her favourite pieces are the grapes and strawberry! Like the above puzzle, she's able to match the pieces to its place.
