which type of toys like children?

Very nice asking! Liking of toys in children is only related with the age group of them. In your case of five year old nephew, I think any spring operated or battery operated or remote control type moving toys are of good choice by them! I hope, these toys are now available everywhere in a city with good affordability! For children upto 2 years, air balls, dolls, audio effect toys etc are to be chosen! For any age group, safety factor of toys with the babies or children is very important during their play! Broken piece of toys are to be discarded for safety grounds! During handling toys, contact with face or mouth by them is to be avoided as well as watched upon! Thanks for this nice topic and best wishes for birthday celebrations!!

I can only speak from experience. Little boys like anything with wheels. A bike, a toy car, just make sure it has wheels. Little boys have great imaginations.
