How often do you buy toys for your kids?

As for me, I buy toys whenever my kid's toys are not suited for his age anymore. Say when we was 5, i bought him a big toy car where he can ride in it. Now that he is 6, he is more fond of remote-operated cars. As much as I want to give in and buy the toys he wants, I made it a point to let him know about saving and learning to value what he has. With that, he usually do not ask too much and even say "mama bili ako pag may pera na". That's so sweet of him.
