Jack went for his 6 month check-up today. He weighs 19lbs 2oz and he is 28 inches tall. He is the size of an average 9 month old. The doctor said "I expect he will be an early walker, he already seems ready to go." To which I replied "What do you mean 'early'?" (anything before 1 year is considered early.) I guess we really need to get some baby gates!
