Getting SO Big!

Nicholas is now 6 1/2 months old.  Where is the time going?  He is mostly sleeping through the night, he can sit up on his own, he gets up on all fours as if to crawl (then face plants down!), he is starting on solid foods (we have done cereal, bananas, sweet potatoes, carrots, and peas now) and his most favorite person in the world is his big sister.
