Brooklynn is a little older that 4 months but these are her stats.
Hight: 25.75 in
Weight: 18lbs 5oz
Head Circumference: 44.1 cm
She is in the 97th percentile for her weight! We have a little chunker on our hands! She is so cute I can't even handle it!! Here is a video of her in her excersaucer. There is a little bear on the pattern of the seat and every once in a while she gets a little bit obsessed with it and will stare at it! It is pretty much hilarious!
