Day feedings and night sleep

Hi- I'm just wondering if anyone has any feedback on your eating/sleep routines. My 3mo son has been eating during the day (9am-615pm ish) every 3hrs and then cluster feeds 715, 815, and 915 every night. He'll fall asleep somewhere bw 10/11pm. He wakes up 3 times each night- one always varying, one time somewhere bw 230/330am and again 5/530am to eat and then will sleep off and on (no feeding) until 830am or so. When he wakes up it takes him about 30-60mins to fall back asleep. I don't want to necessarily cut out night feedings all together but I'd like to at least take one or two out so he's only waking up once or twice max. If i feed him every two hours during the day, would that make a difference? Should I let him go longer during the day and truly feed on demand (he won't cry from hunger during the day until about 4hrs later)? I'm not sure what would be best for him, and also help our night situations.
