Since my little boy started to play toy cars and trains, he loved the Thomas and friends train. In the collection he only have few characters of the Thomas and friends such as Thomas, Percy, Annie and Clarabel. His godmother gave him Thomas build and play where he can build Thomas on his own using a tool and play.
To pair up with these toys, I also bought a wooden number train and a wooden train that fits in the rails so that he can play it along with Thomas and friends. From the book sale, I was lucky to find Thomas and friends books. He was able to identify other Thomas and friends characters from the book. There is also a story of each character on the book. Sometimes he borrowed my laptop to watch Thomas and friends in youtube so to avoid clicking other videos not recommended for children, I just downloaded some educational videos of Thomas and friends.
