Things need to happen in a home without her initiating it. And maybe that's the way she needs to phrase it with him.
I do think that's a
great way to put it! But I also think that there will be a necessary intermediate step during which he'll need some instruction. Her DH has been spoiled for a long time! I'm sure he's capable of learning how to help without asking - but first, he'll have to learn to help
at all.
And OP - There is hope. I was a SAHM for 7 years, and my DH, though quite competent, did get kind of used to not having to do much housework - because that's what worked for us
in that time period. We made a
joint decision that we would divide things along "traditional" lines for a while, to avoid putting DS in daycare. (Please note - I
don't think that's inherently wrong; WE just didn't want a busy life right then!)
But once I went back to work part time, we re-negotiated. And when I increased my schedule, we re-negotiated again. And when his company went to work-from-home, we re-negotiated
again...I'm sure you're seeing the pattern here. What worked for your family in one stage, does not work in another.
It does sound like he's willing to pitch in more, though. So start with doing just what he suggested - ask him to do a few tasks here and there. (And don't critique how he does them.) Schedule something that takes you out of the house, so he has to watch your DS. (Trust me, it's good for both of them!)
And if little-by-little doesn't work, pick a day and make a list of every single tiny thing you do. Have him do the same. Set up a time to show them to each other. He'll probably be
amazed at the length of your list. (You also
might find some surprise items that you didn't realize he was doing. - I definitely think men and women typically notice different things.) Then you work together to divide the list fairly into four categories:
the things you will be in charge of,
the things he will be on charge of,
the things that will be outsourced,
the things that don't really need to be done.
Be prepared for his idea of "things that don't really need to be done" to be slightly different than yours. Also be prepared for the possibility that he'll look at your list and want to explore the idea of you quitting your job. (I can't say whether that's a good idea in your case or not, but it is something he
might suggest, that you definitely don't want to be blindsided by.)
And one final piece of advice - get some sleep!!
Everything is worse when you're tired.
