For those of you who have raised a baby, at what age did your baby usually start walking?

For those of you who have raised a baby, at what age did your baby usually start walking?

I've heard that it's really hard when a baby starts walking, so I'm worried. I'm wondering if it's better for them to walk a little later, or if my child is just late...

So, I am asking this question. If anyone has experience with this, please answer!
