DH and I make pretty well the same salary (within $50/year of each other), we don't *need* the 2nd income but we like our current lifestyle and have a comfortable savings put away each month for ourselves and both children. I will be going back to work regardless, it is just a question of moving up the timetable and having DH spend the last 5 or so months with the kids as primary carer instead of me; I tried being a SAHM when DS was a baby and it isn't good for my mental health.
I am torn. It is a great opportunity, and moves up my career goals by a couple of years. It means more money and an even more flexible schedule. But we went through so much to have DD I don't really want to miss out. I've been telling myself I won't miss too much since I can WFH most days and DH should get the chance to be there for this time too. If I don't take it, DH doesn't get any leave (as I will use it all), if I do take it, I can still be here for most days (DH cannot WFH).
I get that this is time we can't get back, that is why I'm hesitating. :/
ETA: I made it sound like all positives, but the role would mean more responsibility and occasionally longer hours.
ETA (again): Also, I have a slight resentment that with DS I put my career on hold and we never considered that DH stay home. This time because of this opportunity DH has suggested that he finish the leave since it is beneficial to the whole family. Blah! I don't know
