Hmmm I'm not too much of a fan of Tyson. It makes me think of Mike Tyson and boxers (the dog that is since I know many Boxer owners who used that name countless times)..but as other people suggested...Malakai or even Kai sounds cute for a little boy and I really like it. I don't why, but it seems like Kai fits in smoothly with your girls' names and sounds really cute.
