Ay mama, I totally get it, pag effective talaga something, gusto nating ituloy, lalo na kung nawawala na yung problema! Pero honestly, if the label says hindi recommended beyond 1 week, that's there for a reason kaya better check with your pedia about safe long-term use para sa kids, especially sa sensitive areas like underarms. A few of my mum friends have dealt with similar odor issues at yung iba nag-try ng gentler alternatives or pag-adjust ng bathing routine instead, para hindi ma-rely long-term sa strong cleansers, pero bawat kid is different talaga, so your doctor can recommend what's safe for your son specifically. The good news is naka-control na yung issue with betadine, so doc can probably suggest a safer maintenance option na pwede everyday!
