I don't think we will get one in our house. Not for many years at least. Our DS1 is almost 5. Earlier this year we visited relatives overseas and they had a Nintendo Wii. He played it with some older cousins and seemed to get instantly addicted to it and very aggressive and emotional when he was told it was time to stop. I'd never seen him react like that to any other activity ending, and I just don't want to deal with it on a regular basis at home.
How realistic is it to think we can avoid having video gaming consoles in our house with 3 boys? Lol
(DS2 is almost 3, and we have a 3rd baby boy on the way)
