I think the average age children start walking (that I've noticed) is 12 to 15 months. If she is showing an interest in walking she will get there eventually. She just has to practice and you can help her by holding her up but that's about it really. My daughter was an early Walker but she did that completely on her own. I had nothing to do with it!! LOL
I got my baby boy to walk at 9 months kept standing him up and had a new toy in the air and kept stepping backwards with the toy he would try to step and we kept doing it over and over and I would help hold him up for like 2 secs to give him a push that’s how he started walking did it for a couple days and he got the hang of it I was so happy
