This little boy is 4 months old. Holy moly! He loves to drool, laugh, smile and sit up (with some help). He loves his big sis and his little face is changing every day. He has little arm rolls and leg rolls and is just about 40% for both height and weight. He had his first real fever on the day of his 4th month birthday. So he spent the next day at the hospital getting blood work, and luckily it turned out to (only) be an upper respiratory infection. So he had a week of being stuck home with mom and dad, but he was always his happy little self.
