Ay, common yan sa babies lalo na kapag dry skin or winter time! Pero I'd suggest checking with your pedia just to be sure kung may underlying cause, could be eczema, allergic reaction, or just normal peeling na mawawala lang. In the meantime, try keeping baby's hands moisturized with a gentle lotion after baths, at make sure hindi siya sobrang init o umiihay. Kung may redness, itching, o hindi nawala after a week or two, definitely go to the doctor na para peace of mind mo.
