I think B or C or some combination or variation thereof is fine – as long as you understand that when your kids are grown, your earning power will be less than it would have been if you had stayed with your previous publishing company (or returned now to a similar position).
I’m a lot older than you, and I don’t have a doctorate. But I have been working for decades as a scientific writer and editor. I downsized my career by choice and because in my time, and in the place where we lived, there were fewer good child care opportunities than there are for you today. (My kids did not have special needs.) I was always able to earn money as a freelancer or in a work-from-home role – and you will earn considerably more because there will be projects available to you, with your qualifications, that would not have been available to me. But as a freelancer or part-timer, you are unlikely to develop skills that would prepare you for higher-level management roles. You’ll do interesting work, but you won’t progress on a career path.
Freelancers and work-from-home people do projects. They do not, typically, manage and coordinate the work of groups. And this is a limitation. For me, the limitation mostly affected earning potential. I didn’t have any particular desire to be a manager. For you, there might also be resentment because you have been in a management role and perhaps you like it.
Fast-forward a couple of decades, and you’ll probably find yourself doing the sort of thing I’m doing now (although with more pay thanks to your PhD) – working on individual projects at a full-time job under the supervision of someone a generation younger than you, who makes at least 50 percent more than you do – possibly 100 percent more.
For me this was OK. It may be OK with you, too. You have conflicting priorities to juggle, and the compromise may seem perfectly reasonable. But make sure that it’s OK with your husband, too. It’s not OK with mine. My choices were OK with him when the kids were young, but he either didn’t see or didn’t believe the long-term consequences that I knew were coming at the other end of the parenting trail. Now he resents me because I don’t pull my weight in the family financially.
So I think you and your husband need to make a joint decision – with your eyes wide open to what’s likely to happen in the future. Also (although this would have been unthinkable in my time), perhaps your conversation needs to include the possibility that he, rather than you, would downsize his career. Who knows? He might be interested in that option.
