Breastfeeding mommy's of more than one child

Jessica
How do you do it?!?!? I'm seriously so ready to give up! I went 2 months with my first child, no problem, and dried up when I returned to work and couldn't pump. This time, I never seem to have time to pump so I'm losing my supply. I've tried everything and I just can't find the time to keep it going. Any advice?
