What's the longest you breastfed with a genuinely low supply?

[LastNerve1]

Suffering from actual low supply here. Bubs will be 10 months soon and we have been combi feeding but he is needing more formula. I'm keen to BF for as long as possible but feel like I'm going to gradually just dry out. Has anyone managed to BF for more than 1 yr with actual low supply? I've already been seen by an IBCLC and I promise I actually have low milk supply before anyone suggests a supplement or skin to skin or putting him to the breast lots- I am doing all those things as much as I can :)

I've not had genuine low supply and I know how rare that actually is.

Hopefully someone will be along soon who has been through similar

About a month - I was pregnant again though.
Not sure what you can do - I drank a lot of Breastfeeding tea with fenugreek in but even then it wasn't enough once my body had decided nah you're nearly second trimester, not playing anymore. tandem feeding when DC3 was born lasted a couple of months before I then said nah, I'm not playing anymore
