Are there ways to increase breast milk? I know that lactation teas are a myth, what helped anyone? I often hold the baby close, he can hang on for an hour at the breast, sleeps with the breast and sucks very long at night. I do not do anything, I rest, only thing is that I can't sleep because I can't fall asleep with the baby on my chest.
