I don't work nights but my DH does every 3 weeks. The other 2 weeks, he works days. However in our situation, DH works full-time and night shift also means the weekend of that week as well. DH is in the military so we can't change it immediately. We have to wait for a posting and thankfully we have one so after Christmas he is no longer on shiftwork.

My personal situation is I hate being the partner of a nighshift worker. I get very little support when looking after the boys as he is so tired. He feeds the youngest in the morning then sits in front of the TV trying to interact with the boys so they can see him at least a little that week. My DH is a person that needs a lot of sleep so this may not apply to you.

It does sound like you have thought it through and have a lot of support prepared. All I can suggest is trial it and see how you go.
