Pls do not judge

I have been breastfeeding baby since birth she’s 2 months now

But recently my low has decreased so she refuses to latch so have substituted with pumped milk and formula

I hardly manage to pump 90ml a day so jus one feed

I feel like im trying too hard and should stop as it’s so time consuming

But then im glad I give baby atleast one feed

FYI seen lactation consultant too but it’s of no use

Wat should I do
