I'm 6 months old!

Here's my newest trick...I can sit (for less than 5 min at a time)
My Dr.'s visit went well!
20 3/4 in long
17# 2 oz
My weight is average...but I'm tall!
(the Dr. said my height compares with the average 12 month old!)
So here's the deal...
the Dr. said as I sit and build my sitting muscles that should lead to crawling.
On average children crawl between 8 and 10 months...
So here's another chance to put a date in the pot...check the comments for my mom's guess! ;)
p.s. I can scoot on my tummy in circles and in reverse...to get to my toys...
