10.5 months. So close but so far

So

So my baby (10.5 months) has been refusing his 530 pm nursing for two weeks now i think bc of my low supply n it takes forever to suck (the other times he nurses are also his sleep and nap times so he sucks one hour each time). I try to give him my nipple but he just wont.

Problem is he also doesnt take any bottle or cup so i cant replace that missed nursing session with formula.

So now its been two weeks that he only nurses three times a day (1030, 130, 8). He also nurses a few times at night but that hasnt increased since he stopped his 530pm nursing session.

I don't know what i should do? Should i just let him be?

Breastfeeding with low supply is the most stressful thing ever.
