You have my sympathies. The final stages of a phd are relentless.
I am not sure if your dh qualifies in this instance but I do, having been one, have sympathy for people whose partners are doing phds. It can be a pretty lonely existence too.
You "lose" your partner, especially in the final stages, for clear and obvious reasons but you still lose them. Everyone is very impressed by them and the very clever work that they are doing but don't see what goes on behind the scenes to support them (which is why I say your dh doesn't really qualify).
I supported my dh financially, emotionally and practically throughout the period when he wrote up his phd. I was a probationer teacher at the time so had mountains of work to do myself every evening, yet I cooked, cleaned, read and corrected his work etc.
No one made a big fuss about what I had done, or the lonely hours that I had spent, but they made a huge fuss of him, quite rightly, when he passed.
I see my BIL in the same situation now. My SIL is in the final stages of qualifying in her line of work after years and years of study. Everyone praises her and makes a fuss yet BIL is the one who has done a full time job, shopped, cooked, cleaned, dealt with panics and tantrums, lost his social life etc. He is very proud of her too, as he should be, but these courses often impact on everyone, not just the person studying.
All that said, I don't think your dh is behaving very respectfully or fairly. It does sound like he sees you as a SAHM and your course as a wee thing to keep you entertained and I do think you should try to have an honest and frank discussion with him and to share the home and child care responsibilities more fairly. If he doesnt want dd in childcare more then he will have to provide an alternative as you have work to do!
Good luck!
