I try to limit handling/stress on my babies and usually suggest people handle them no more than 5-10 minutes 2-3 times per week until they are over 20g. The stress of being handled and having their temperature fluctuate can take calories away from growing and possibly affect their appetite.
I made my own Leo a playpen very similar to this one. They don't need something super complicated. Maybe in a few years change it up a bit just to give him something new.
