No sleep 3 month old ALWAYS hungry 😴

Help, my LO is exclusively breastfed and the last few weeks all he does is feed! Literally it can be every hour of the day and night, sometimes more. It’s exhausting to the point I wanna quit breastfeeding but he won’t take a bottle 💔 I’m tired and just wish I could satisfy his hunger. He used to sleep so well at night but now he won’t go back down because he’s still hungry. He’s a big boy for his age anyway but it never used to be like this. Anyone else having/had this?
