I will add that daycare has really been villified by not only the Christian right in this country but other sects also.
In my opinion, this is purely a cultural value thing - sprung out of the idea of the “nuclear family” (an American ideal) and reminiscient of “homesteading” and adopted by Christianity, where a family moved out to a plot of land in the west, the father plowed the fields, and the mother raised the children. That was the community division of labor.
In other cultures, men and women do go off to “work” - men hunt and women gather and the children are cared for in settings by grandparents/elders. They grow up nutured and develop into functional adults. Grandparents of course, don’t play that role in our culture - their role is to, well. . . fill up cruise ships and migrate to Florida

.
Seriously, it may sound cliche but “it takes a village to raise a child” is an appropriate saying to think of when you think of daycare.
In other words, it’s not a place where forgotten kids are left by irresponsible adults. It will be a place where friendships are formed, socialization is learned, academics fostered, and an appreciation of adult authority is gained.
Your husband being a teacher will be invaluable from 2 aspects though - great health benefits and over the years, and having the summers off will be of great help to you so it may not be prudent to have him be a stay-at-home Dad
As far as your sister - tell her to go pound sand and mind her own beeswax.
Charitably, of course.
It’s an interesting discussion, one that is broader than appears on the surface. One thing I will say is your greater income potential will make your relationship at risk for problems in the future. It’s becoming a greater and greater problem - women wanted to go out into the workplace and succeed.
And they did.
But in the end, it’s not what they really wanted - they also wanted to stay home and be a good mom and see their children grow up (so yes, that is the loss you will have). But by then, men had been displaced from many jobs in the workplace and now the traditional role of provider of the father/husband has been disrupted - if you want an average house (I think a 1/4 million in the US) in an averagely safe neighborhood with health benefit protection, 2 incomes is the norm.
What then I have seen happen, and I have much contact with a lot of people in my line of work, is the woman starts to subconsciously resent her husband’s lack of ability to provide well. Intellectually, they understand the problem but emotionally, they want to be at home with their kids and yet, when they are teenagers to be able to walk back into their career as if nothing had happened, that the world hadn’t changed.
I am not saying you are going down this line of thinking or will but just making a cultural commentary if anything. Pure generalizations (which I think are accurate).
It’s interesting to see what we are reaping after what our parents sewn in the 70’s.
As a Generation X member, I am actually starting to become more openly critical of the generation before me after receiving much criticism over the years as being spoiled. To me, the generation before “X” had the pill, they partied, they borrowed money like it was going out of style and now my generation and unfortunately, probably my kids will have to pay for what was sewn.
Sorry if I drifted the topic.
Good luck.
