Re: Supply issues
Or risk mastitis! Pumping at work - for 12 hours - is not just about feeding the baby, but about keeping YOU healthy. Going more than 4 hours at this age puts you at increased risk of mastitis, and believe me you'll be missing work if that happens
Also remember that your milk supply is regulating, so you might not feel engorged or leaky anymore (if you did before). It doesn't mean you're losing your supply, rather that your body isn't making so much extra. If you're pumping on your days off every day, then your body thinks you need however much baby needs + 5 oz. so on your work days, your engorgement is going to be even more.
