When did your baby start waving?

I have no clue what the average is but my 11 1/2 month old son does not wave yet. He doesn't point either.... He is right on target with all other milestones, pulls up, stands independently without holding onto smoething, crawling, using sippy cup only, etc. But still no waving... I try to get him to do it every day but he does the same thing... just gives me a blank look lol
