We have often said that we want to get to a place where hubby could be the SAHD for a while and I'd go back to work. With hubby getting closer to retirement age, we might let him retire early and I'll go back to work long enough to qualify for my own retirement benefits.
Oh, there would be an adjustment period. He'd get lost in the computer all day. Already he has moments where he thinks I do nothing but sit at home and eat bonbons all day (okay, some days are pretty lax! - one of the perks of my job). And we would definitely concentrate on different aspects. For instance, more projects around the house would probably get done but the quality of our eating would go down. And like a SAHM he would go through the inevitable depression-phase because it is really hard to stay focused and motivated when your job never ends and you have no defined goals. Plus I think it is harder for SAHDs because they don't have the same opportunities for socialization as moms do, and even our opportunities are rare. Look at the SAHDs who have tried to join this forum - it just doesn't happen. Hubby is like that. He wouldn't reach out and be social on purpose.
But hubby would have one benefit that I never did ... a spouse that has been there and understands what he is going through.
He is a great dad and DD would love to have him home all the time.
