You could also put his hands in mittens, or the fold over thing on bonds onesies. I did that a bit in the early days cos it freaked me out too (but he didn’t do any damage to reassure you!) we also use a little electric file for his nails so there’s less chance of scratching
My little does this too, and so far, she has not hurt herself...and she really digs in. So he should be alright.
