Since yesterday, my breasts have been incredibly soft ?, usually they were full every 2-3 hours, slightly firm and milk flowed straight out. Now there's none (is this normal? I still fed one breast all night, in the morning the second was full, so I got only 50ml ?). The next time I switched breasts, I squeezed out 200ml from another breast.
