Yep, the trick is super simple: WAIT....until he is ready. Boys tend to be a bit slower at things, sometimes. So give him at least until he is 14 or 15months. Meanwhile continue to walk him holding his hands, thats great. And let him cruise around the furniture. He will venture out and take steps on his own before you know it.
No worries, he is fine. :)
ps and remember once they start walking they are into wayyyy more things, so dont push it, lol.
