This is both Pearl and Axel at 4 months old!
Both of them have massive bald heads. Pearl's head was in the 97% for size and Axel's is in the 100% range. I don't fully understand what that means except that they both have large heads.
Pearl weighed 15 lbs 2.5 oz and Axel weighs 16 lbs.
Pearl was 24.75" long and Axel is 25".
