Sean 4 months old

Sean is quite the baby little boy!    He loves to watch his older brothers play and coos and giggles at them.    He had his 4 month check and his stats are:

Height: 24 1/4 inches (25%)
Weight: 12lbs 12ozs (10-25%)
Head Circumference 40cm (5-10%)  small head, just like the rest of the Tillberry boys!

We were told that he could start cereal this weekend.   I remember all the other boys started cereral at 4 months and I was always so exctied, but when I look at Sean I feel that he is just too little.     I think I am already trying to keep him a little baby forever!
