Having to do more housework and be more of a parent in the mornings isn't a good enough reason to stop another adult working.
Sorry.
"Her job may be a 2hr commute away which means that he had to do all drop offs and pick ups, which in turn may mean he has to give up other things such as a hobby, while OP gets to carry on with hers unaffected."
Yes, a woman should give up her livelihood so that a man can keep up the hobbies he enjoys.
Fucking hell.
Period - I'm glad you, at least, have the cop on to realise that you don't need to take on your husband's unhappiness about this.
If you feel sad about leaving your baby, then that is entirely reasonable.
But he had his chance to feel sad about that months ago. Now he's at work all day and is quite used to leaving her all day. His "unhappiness" at you working is not something to be feeling guilty about.
And neither is, for that matter, your need to go back to work. Or to leave her in childcare.
Be sad about it, find childcare you are happier with if you don't like the nursery, figure out a way not to work if you can do that.
But GUILT about earning money for your family is a pointless and wasted emotion.
