Our sweet baby boy is already four months old. He went yesterday for his check-up and he weighs 16 lbs. 2 oz. He weighs more than Jesse (15 lbs) or Bailey (14 lbs. 12 oz.) did at four months. So he is a big boy! At four months he is laughing, smiling and talking all the time. He is sleeping through the night from 9pm-6:30 or 7am. Thank goodness! He is rolling over from his stomach to his back. He is also reaching and playing with toys. And his is now to the point that he starts to cry if I put him down and walk away from him. He still loves the swing and normally takes his morning nap there. Bailey and Jesse continue to dote on him most of the day. We love our sweet Jack and can't wait to see him grow this next month!
