We decided to get a walker for Tyler.  (We have it in the kitchen, so there's no safety issue.)  He really seems to like it, although the first time we put him in it and he moved it, he was so startled that he started to cry.  But it didn't take him long to figure out that if he kicks out with his feet, he can move himself backward.  Of course, now I am constantly having to rescue him when he gets himself backed up against the wall, or the fridge, or whatever and starts getting frustrated because he can't move any more. :)  Eventually he'll figure out how to go forward...
