@FolkSongSweet, my apologies, I hadn't realised your DH is at home more. I don't consider that outsourcing and have certainly see plenty of happy kids where dad is the one that is home more.
My DH went to 4 days a week teaching when we had my eldest, but was also a district councillor. He also moved to a state school - much shorter hours. This allowed him to be around for DC on one of my working days and to be the one that did nursery pick ups and later school run (she's now in year 2). Then he'd go out to meetings and do council work in the evenings - most meetings start at 7pm, so I'd be home and we'd all have dinner together then he'd go out. We also moved very close to my parents - they were happy to look after DD one or two days until she was 2.5 and we wanted her to do 2 days of nursery.
When my twins came along it was a little more complicated. My mum was still happy to do one day a week, but with 2 of them they are more of a handful! We do have a nanny that looks after them 2 days a week term time. Is that as good as being looked after by family? Nope. Not in my opinion, and that's with a lot of experience, and there's plenty of research behind that too. I don't claim to be perfect though! I chose not to reduce my hours because I have kind of "paused" my career, but I'm not ok to give it up all together. I am lucky enough to still have very long holidays with my children.
DC#4 may well get the short end of the stick! I will have to be working 4 days and DH will be full time at school (no longer on the council after the local elections, which probably tells you his party!). Neither of us can afford to cut hours as we will have DD's school fees, and DTwins will probably be doing preschool on 4 days. The best case scenario for DC#4 will be 2 days with the nanny and 2 days with grandparents, but that depends on how they are feeling - they are now in their 70s, although still very active.
Career-wise, basically I've put things on hold since I had children. It really hasn't been possible to push for promotions in the same way as I would have done, and I'm not quite where I'd like to be. I'm not unhappy though. Honestly, I don't feel I could do more than my current role with the time that I have - I work when the children are sleeping or at weekends when DH has time to take out all 3 sometimes.
So I don't quite have it all. I'm very lucky with what I have and my career is not bad, but not currently progressing. Some times I worry - I'll be 40 when I'm in a position to start pushing again, and the people that are mostly getting the roles I would want seem to be men that are mid-thirties and have a wife at home.... I also spend very little time with DH - either one of us has the kids while the other works, or one is doing something with my eldest (homework or music practice, or DH does board games with her as he's a good chess player) while the other has the toddlers for something more physical. My house is also often quite disorganised and there's always flipping laundry drying somewhere. Admittedly, that side of things could be outsourced - I suspect of you're going for partner you're on a better wage than a teacher!
