My first son started walking at 10 1/2 months
My daughter started at 9 1/2 months (right before 10 months)
My twin son started walking at 8 1/2, almost 9 months.
My twin daugther didnt start walking till about 13 months.
I know my daughter started pulling her self up to stand at about 6 months took her first step holding on to the couch at 7 months. I don't remember when she stood up on her with out holding on but she took her first step with out holding on when she was 12 1/2 months.
My son started pulling up around 8 months and the week he turned 10 months i was letting him walk while holding his hand and he pushed my hand away and started walking.
