Quitting pumping/nursing?

I’m a mom of 2. My oldest is 18 months and my youngest is 2 months. I have about 1,000 oz of milk frozen and my baby mainly nurses.

I’m struggling with pumping and nursing mentally. I can’t wear what I want/have due to leaking and baby nursing in general. It’s affecting my body image and definitely intimacy.

I did think about slowly dropping my day pumps/nursing sessions. And just doing it at night.

I’m mainly just wondering if that many oz would be enough until she turns 1 year. On her birthday I’m planning on giving milk and juice only no breast milk like J did with my first (formula fed though).
