breastfeeding dilemma

hello mommies i’m a ftm and my lo is 4 months old , i want to breastfeed for a year maybe longer !! but my supply has dipped !! my baby will only nurse when he first wakes up in the morning and that’s it !! if i try to nurse him any other time he gets fussy at the boob and i pump he prefers the bottle but as long as he’s happy i’m happy !! i’ve had to supplement formula for my baby because my supply has dipped so much when i pump i get between 1oz-3oz total (from both breasts) and at least it’s something !!! can i reboost my supply i use to get 10oz total from each breast when he was smaller 😭😭 i know it’s supply and demand but it’s hard when your LO prefers the bottle !! any suggestions on how to instantly boost my supply i had half a body armor the other night and pumped 4oz after that i was like 😳😳😳 this is a miracle , should i continue to drink those ?? should i just pump more ?? i don’t have milk bags , so if i pump more 9/10 i’ll just get a few drops between the times i normally pump , very heartbreaking i want to pump for as long as i can and i WONT give up 😖😖 advice please i’ll take anything
