My 4 years old son is been obsessed with Thomas the tank engine train set for more than 2 years and also loves cranes excessively because of the hooks that are attached to them. Will playing with just these toys restrict his brain development and should I stop buying them?

Hi many thanks for everyone responded to my question I would like to explain the reason of my concern, this is because of a relative of mine whose only toy he would play with is washing machine till now at his early teenage years he is still like to watch it spinning. The problem rises to a level that he would not play or socialize with the school children during his nursery and primary school years but rather stay indoors playing with the pretend toy machine. Sometimes he would take a plastic bottle fill it with water and tiny bits of strings or fabric then spin and shake it all day long sitting alone. When he is watching something on the internet he would watch some clips only about washing machine. So with my son he would associate lots of things as trains or crane, I’m just not sure about him if he’s behaving normal and maybe I’ll observe him how he progress and he would behave with friends.
