That kitten looks to be about 2 weeks old. I don't know if you already are, but make sure you are bottle feeding it still! C: Kittens need to be bottle fed until they are about 4-6 weeks old and then completely weaned off when they are 8-10 weeks (I foster kittens all the time, so I know quite a bit about the little critters. )
Anywhoo, here's a few names..
-Winnie
-Minnie
-Charlie
-Elaine
-Lilly
-Benny
