9 months

Seth weighed 18 lbs 14.5 oz (37%) and was 27.75 inches long (25%) though I don't believe this one since he has definitely grown and has been tracking slightly above average in height (he was 27" at 6 months). 18.5" head (94%). He can crawl fast, cruise, squat to pick stuff up, stand without assistance, walk with help, and say mamamam and bababa. Still wakes up a few times a night. He has 4 teeth and shows us them in his smiles a lot!
