Milk supply question

Tiffany

My baby is 8 weeks and starting to sleep 7 hours at night. And I’m sooo happy. But my boobs. Not so much. I get engorged and have to express a little so I can feed him. And now I’m worried, since he’s sleeping longer will my supply start dropping? He still eats every 2-3 hours during the day. Need some help! Thank you!
