At 4 months old Louis is:
17.3 lbs (92%)
26 inches (80%)
43.5 head (97%)
He wears size 3 diapers, and 6-9 or 9 month clothes. He has really started to love sitting in his bumbo and activity saucer. He laughs a lot, especially at his Daddy! He already loves to play with toys and is now a pro at using his hands to bat at, and grab toys and put them in his mouth. He is starting to show interest in table food, so I am thinking at 5 months I may introduce cereal. :-)
Not a huge difference in size from last months snapshot, but I think his blossoming personality really shows in this months photo! He really does have the best personality.
