5 month old still in 4 month sleep regression 🤱🏻😭

So my son still eats every 2 hours during the day. He is exclusively breastfed. He doesn’t nap more than 20-30 min at a time unless he uses me like a binky.. during the night, he’s also waking up every 2 hours or less to eat. I’ve tried just rocking him to sleep, but he will stay awake. I once just tried rocking him for 1 hour and 45 min and he still was awake, so I gave in and fed him. He was starting to sleep so well before this.. my SO is currently in a different country. Any suggestions ? Also I will not use the cry it out method.
