Re: illness and decreased supply
It's hard to say. For some moms, supply does bounce back up after the end of their period and/or illness. For others, the only way to regain the ground they have lost is to put in a lot of work with the pump or nurse the baby a lot more frequently. I hate to tell a busy mommy to add more pumping/nursing time to her schedule, but I strongly suggest that you do it if you possible can.
