I've used Aspen for over 30 years and had no issues. I also feed in my enclosures. Sometimes a snake may eat a piece of wood, but it always has passed. If I was worried about my snake eating a piece of aspen after eating a regurged piece of food, I think I would be more concerned why my snake was regurging the food. As for the babies, the wood chips are normally to big for them to eat anyway. I myself keep my babies on paper towels, it is just easier to find them. But as I always say, there are many ways that work, so do what works best for you.
