Why Wont He Sleep.?? Help.!?

Soo my son is 7 months and he slept through the night great until we moved when he was 5 months. Then he was up every 3 hours to an hour and I've just been getting up since then. Sometimes he's hungry sometimes he needs to be changed and sometimes he's just wide awake. I've tried minimizing his naps to completely taking them away and he still would get up. Now I've been letting him sleep with me. So Everytime he wakes up I just rock him to sleep and he's good for another couple hours. So hasn't really stopped anything but me having to walk to his crib. I don't know what else to do to keep him asleep. 😭 I've had him cry himself to sleep which sucks but he still wakes up a couple hours later.

HELPPPPPP.! Please
