For the very first time, Terry able to solve puzzle all by himself. There are 4 sets of puzzle in it in different of 3 to 6 pieces. This was his great achievement over the week. He first have this during his ward days. (Thanks for that Sasha). He loves it till today and still playing it everyday even he know how to solve all that.
When the first time I solved it for him, he gets angry when he wants to hold them up, as he did all the pieces are break off. He brings that to me everyday and particularly want me to put up the train and car for him only. He watched me do and I not even step by step teach him how to join up piece by piece. Few days ago, he surprised me by joining up all 4 sets by himself after one another.
