How often do you buy toys for your kids?

My Tita used to buy toys for my cousin almost every month (now 10 years old). She said that as long as she can afford, she will buy her the toys that she likes. She said that she wants to give all that she can to her little one as long as she can because when she was a kid, her parents weren't able to buy her a lot of toys due to financial incapabilities. So, now that she is in a good state, she wants to give her little princess all that she can afford.
