What do you think happens in the end? Does the child find his parents?

Towards the end, I think that the child reunites with his parents. The man who found the boy crying picked him up and showed him around the fair to cheer him up. As the child only wanted his parents, I feel that the man would try to search for his parents and try his best to unite them. The parents would also soon realise that their son was missing and would definitely search for him too.
