Good for him!!
Now the fun starts!! I have a 3 year old and (almost) 2 year old twins and they keep me busy. All 3 of them run in different directions!
I definitely am liking the toddler stage much better than the baby days, but that's just my opinion.
My babies were all early walkers as well. My first son walked a week before he turned 10 months old. My boy twin walked the night before he turned NINE months old and his twin sister walked exactly at 10 months.
They haven't looked back since!!
Have fun!!
