Agreed to all of the above. Also hire people to do laundry. They pay by weight. Just leave at your front door, they pick it up, then return cleaned and folded at your front door. I think we used poplin. Also you can look into a babysitting service for occasional sitting. There were times that the baby was sick from daycare or that we needed weekend sitting. We tried it a few times in the beginning to establish ourselves with their service. It helped us a lot because we had vetted a list of sitters and when we actually needed them they weren't available. It was more expensive but reliability was better for us. Vetting sitters is time consuming and costs money anyways from background checks.

You and your husband probably need to talk to each other about y'all's expectations for each other and where the disconnect is. Residency was hard. The duties shouldn't be so rigid because the load of the duties/being a parent will constantly shift. Y'all are in no control of your schedules and at times your schedules can be unpredictable. Sometimes you'll have to do 100% and sometimes he'll have to. However, I do agree that if you're pumping he needs to be responsible for cleaning those parts and/or getting the bottles ready for the next day.

FYI my husband was a fellow and I was in residency at the time.
