Playstation 3??

My mother decided that she was going to get my kids a playstation 3 for christmas. My question is does it have any games for 5-6 year old kids? I have a 6 year old girl and the boy is 5. I also have an 11 year old and 9 year old boy.
I have a Wii. Who knows why my mom got the playstation 3 for them. I was hoping playstation would have some kid titles.
