If your girl has been getting plenty of wet nappies, you're doing well
dont't judge your supply by how much you pump as babies are far more efficient than pumps. From my experience I can never pump more than 60ml in total from both breasts, yet I am still breastfeeding my 21 month old.
Go with the flow, latch baby on whenever she wants or whenever you're not sure of what she wants. Easiest way to settle them for sure and less stress for you.
