one of my friends bought sth like the Train Puzzle (not from this company, but made in Malta) to my baby. Baby's fingers can grasp the items but he doesn't like playing in the "supposed" way. instead, after lifting two or three items from the board, he will turn the board upside down and removes all the items and then proceed eating them.
i m not sure if he is not up to the age to play similar toys yet.
and i never saw him trying to putting the items back onto the board.
