4 month old, suddenly waking 3-4x/night

Zach has always been a wonderful sleeper. Up until this past week he has slept 10-11 hours a night no problems at all. no wakenings.
Then now all of a sudden, he's begun waking up at about 1am and then another 3 times after that, erratically. i shhh-pat him to bed and he falls asleep without being picked up. he is quite a big baby - 16lbs - so i thought maybe he's getting hungry through the night.

his schedule is like this:
E - 7am
A - 7:30
S - 9:00

E 10:00
A 10:30
S 12:00

E 1:00
A 1:30
S 3:00

E 4:00
A 430
S 6:00 - catnap

E 7:00
A 7:30
S 9:00 Bedtime

He has never taken a dream feed in the past and it has never affected him before. thank you so much!!!

I think Zach is probably really tired.  Has he always slept for only one hour?  Sometimes those "shorter" naps don't help them get as rested as longer ones.  Does he eat again after 7:00?

he doesn't have a pacifier or any other props.
he usually only sleep for 1 hour or so but sometimes in the early afternoon he'll sleep for a longer period of time (2 hours). He usually wakes himself up after 45 mins or 1 hour of napping.
oops... i forgot to put in my schedule that he also eats at 8:30pm before going to bed. but he doesn't fall asleep while nursing. he falls asleep on his own.

He still seems to like eating every 3 hours, so how do I move to a 4hr EASY? how do I know if he's ready and how do i start the transition?
