Parker is 4 months old! He hasn't had his 4 month check up yet so I don't know if he is big or small but he is just getting into 3-6month clothes and he wears size 2 diapers. So I am guessing he is in the 25-50percentile. He laughs more then my girls did but he is pretty moody. Jesse says he is more like me because he has no patience. Parker is very close to rolling from back to tummy and he keeps trying to hold his head up like he wants to sit up. He has the sweatiest feet and hands ever(which he gets from Jesse)and he doesn't sleep through the night but oh do I love this little boy!!!
