J.N.
I never really did much, beyond a bit of encouraging talk ("come on, come to mama"). My kids were all early walkers (8-11 months) so I never really felt the need. I've seen other moms give their kids one end of something to hold on to, just for confidence, etc, but I never felt it was necessary.
8 months is actually REALLY young for independent walking. If he ends up walking on his own right away, that's fine, but be ready for a 2 or 3 month (or more) wait. He's making all the right steps (no pun intended), and he'll get there when he's ready.
