So I'm (F) a professional partner, which my husband (M), also a professional partner, is fine with. (I'm not giving ages, there's not that many espers and it'd be doxxable. No backlash or power deets either!) Neither of us has sex with our partners (both M), we're monogamous. Recently I took partial leave for almost a year so I could get pregnant and have our first baby - I still showed up to work during that year but I was less effective because I couldn't build up any backlash safely so my partner had a secondary (F) for high power use periods. (I think they were having sex but it's none of my business and not really relevant to my question.) I took a little maternity leave but my husband and I were able to arrange to mostly be at work at different times plus we can afford a nanny so I was back on the job after less than a month.

There are some meds I take when I'm going to be backlashed that mean I have to pump-and-dump (during and for the first little while after my work hours the baby drinks formula and is adjusting great to a mix of breast and bottle). Pumping turns out to be horrible, big surprise there. The medication isn't dangerous to an adult (even one who wasn't prescribed it) in the amounts found in breast milk. So my partner suggested he could drink it. It makes perfect sense, it's a guiding fluid, it's not sexual, (the baby does the same thing!), my partner was actually pretty bad at getting any milk out at first but after a little practice was way pleasanter than the pump. Plus I can be on my phone the whole time instead of having to lean forward and have a hand free to adjust a flange or whatever those things are called, which is really nice for my backlash.

I told my husband about this clever life hack which means we can give that fucking pump to my sister-in-law and I never have to see it again, and he flipped out on me! AITA?
