today my father was helping out and changed LO's diaper. well he wound up pulling down too fast on the onesie and caught DS umbilical stump and it started bleeding. Its not bleeding anymore, just really red

i feel so bad for the lil guy. my question is, do i still go ahead and clean the area with alcohol (wouldnt that burn?) or do i just wipe it clean with warm water? idk what to do now...
