My little man is not so little any more.  He is now 6 months old and 18 lbs 12 oz and 27 1/4 in.  At this point Addy was 16lbs 2 oz and 27 in.  He is so happy most of the time that we feel super blessed to have such happy kids.  He also sprouted his first two teeth the day after he turned 6 months.  He is trying to beat his big sister to all his first milestones.  Addy didn't get teeth or start rolling over until she was 10 months old and Graham already has these both down!!
