It's now 4 weeks since Charles started drinking much less while I was at work. I haven't pumped at work for a week (just at home as-and-when I need to, which I'm finding much less stressful) and tomorrow I'm going to return the keys to the room I was provided, and let my bosses know I won't need a pumping break any more.

I no longer need to pump for my own comfort as my oversupply has eased up in recent months and I'm much happier not scheduling the break at work. I'm keeping up with what Charles drinks while I'm gone and he gets plenty of feeding from me in the afternoons and evenings, so my supply isn't threatened. Work have been generally supportive of my breastfeeding so far, but I don't need to pump at work any more and I'm heartily glad to stop.
