I agree with all the others...once you make the best plan you can make, and have put it into motion, there isn't much to be gained by obsessing or stressing.
If there's a way for you to have a sit down friendly chat with your husband about your perspective and acknowledge that the debt is serious to you but stressing seems counterproductive, I would really suggest you try that. It sounded like maybe he was reacting with fear that you may not be on the same page about attacking the debt...which you clearly are, but him knowing that in his bones will probably help him relax, which in turn will help you relax.
Nobody's answered your question about debt and kids. Obviously both topics are highly personal. I will say that I was married to a non-saver for 15 years and we had three kids together, so we were in debt in the typical American style when we had kids, but we also saved quite a bit too because of my influence. After being on my own for 7 years and saving a lot more and spending a lot less, I've got enough to fund my kids and my life, their college, and my retirement, and I'm only 44.
Personally, I don't think kids cost as much as those articles say they do. As long as you love, feed, clothe, educate, and care for their medical needs, they'll turn out fine and you won't really spend much.(*) You can spend more if you want to. For me, I figured my kids have set back my retirement date by about 5 years between the three of them. Since I'm FI at 44 and my kids are great, I consider it to have been a worthwhile tradeoff.
One other thing I will mention is that Dave Ramsey, who is about as anti-debt as you'll get, prioritizes family (marriage and kids) ahead of money. He'll say that debt isn't a reason to put off getting married or having kids as long as you both are like-minded about getting rid of the debt ASAP, which it sounds like you are.
(*) Although if you have a kid with special medical needs, that can get expensive out the gate. My three are basically healthy.
