With babies, its easier to see poop on kitchen roll than in aspen or anything else. Even if you dig about for poops with aspen you can sometimes miss them but there's no harm in using it. I would just say if you do, don't use a lot or the poo kinda gets buried. Mine are 8 months old and I use like a wood bedding and I still miss a few poops that I only see when I do whole whole substrate change.
the only issue using aspen with small snakes is if you feed inside the viv and the chances of substrate being eaten with the food and causing gut impaction
What everyone else said! I always see people with hatchies in aspen. As staple said, kitchen roll would help you check up on poop but I think they'd appreciate aspen more!

Just thought I would let people know was at my local pet store where they sell all sorts of stuff for larger animals. Asked about the Aspen like stuff for horses mentioned here. Could not remember the name but he showed me a number of bails all looking similar to aspen. Some were not labled so I don't know what was in them but they also had a product called easibed that looked quite good. I contacted the company and they told me it contains a lot of pine so would be a non no fors snakes. Going to write down the name of the other stuff and ask if they can get that tommorrow. Just a warning that not all that looks like aspen is aspen.
