To say that in front of the Inlaws was clumsy and hurtful. I can understand why the OP is upset.
As far as she knew, her dh and she were both happy with the current situation, she does an excellent job of running the home and looking after the children, he does the paid work. The fact that she does all the child care, housework, cooking, organising the home means that he doesn't have to think about it.
She feels that she enjoys this role, and thought that she was valued (and lets not kid ourselves, actually keeping a house nice, organising all the household stuff, and doing a good job of looking after the children/homework/activities IS work, allbeit unpaid). His comments have made her feel undervalued and hurt. Fair enough.
It really saddens me when sahm's get rounded on in the way that the OP has in this thread. She IS doing a good job of looking after her family and home and husband. It's not for everyone, but she values and enjoys this role. She says they have a comfortable lifestyle, and that her dh loves his job...it does not sound as though her dh has grounds to resent her for not working at all.
Some of the posts here are just weird and overly hostile. It seems to be fully acceptable for women to make others feel bad because they have chosen to stay at home and parent their own children, because it is seen as "lazy" and "selfish". What rubbish. It is certainly not possible to do this well by sitting on your backside all day. She's even been mocked because she does photography and attends a book club. Why?! Are sahm's not allowed to have outside interests?! She cant win, if she solely just does house and kids stuff, she's not using her brain, is some sort of 1950's stepford wife, if she does have outside interests, she is a selfish layabout who should get to work immediately.
I suspect that the DH made a throw away comment and hasn't realised how hurt the OP is. I also suspect that the OP probably does EVERYTHING in the house and for the children and dh, and that if she were to work, and these chores had to be shared, the dh would get a shock.
Also re. the comments about the children going to childcare, maybe the op doesnt want them to send them to "wrap around care." And that's ok.
I don't know. I work from home. I do the majority of the house and childcare stuff too, and sometimes I do it all badly. Because it's a lot to do. I DO think that being a sahm, if you do all of the house stuff and stuff for dh and the kids is more than a full time job, and just because it is not paid does not mean it is not a valid choice for those that want to do that.
