I've seen a hatchling at 27g and it is now thriving so it can happen, if you believe he is around 100g now Kayleigh perhaps try upping to the next prey size up (a small one) if he can manage it, they an take more than we give them credit for.

I also don't handle after eating, I leave for 48 hours, it certainly doesn't hurt me leaving them and it's safer for the animals in my opinion.
