Will at 4 mths

Will is 4 months old!!  He is 16 lbs 11 oz and 25 1/2 inches long.  He loves his feet and has been in a swing and airplane for the first time.  He is rolling from his tummy to his back and sticking out his tongue.  He is most of the time a happy baby, only seems to cry when he is hungry.  He is eating every 2 hours during the day and Never at night.  We have started putting him to bed at around 7:30 and he sleeping until I wake him at 6am.  He really won't sleep during the day (which makes for a LONG day for me.)  He seems to only cry when he is hungry and when I put him down for a nap, which he refuses to take!  He is about to grow out of 6 month sleepers and is in 6 month clothes other than that.  He is wearing size 2 diapers.
