The best thing you can do is let your beardie shed on his own and don't do anything to peel off the shed, as this can cause damage. There are some things you can do to try to help a beardie shed a bit better, such as giving baths with warm to the touch but not burning water, but I wouldn't do this more than a couple of times a week personally. Keep an eye out for any shed that isn't coming off after a long time, though.
Shedding can take a while to complete, in any case, and baby beardies will shed quite a bit. once they get older, they start shedding less.
Like I said, do NOT peel off any shed unless you have to, and I would ask here first before you do.
If you have any other questions, we can help you with anything. For example, we can go over your tank setup and feeding schedule to make sure that your beardie is getting the proper care (almost all pet shops and many breeders have very bad or misinformed information).
