I think it's a nice gesture. But I'd be freaked that I was going to break or ruin their stuff.. Plus what happens if they suddenly get pregnant on accident? Then you have to give everything back and get new stuff anyway. It's just risky to me.
I wouldn't accept the stuff if they wanted it back, I would be afraid that it would break down since it's already been used twice and I would have to replace it. I would rather something new especially since you said they have dogs and you are allergic and the stuff isn't even to your taste.
You can always get stuff that you like gently used from Craigslist and consignment stores.
