I haven't breastfed my kid or pumped milk for a year now, but I can still squeeze a few drops from one breast. Is there any way for me to increase my supply even though my kid doesn't latch?

I don't understand. So what do u want this milk for then? Since it sounds like the child has not been drinking bm at all for a year Plus and by now should have established his 3 meals daily solids? Milk is no longer that important as the focus moves over to the solids
