Oo, naririnig ko rin yan sa mga mommy groups, pero honestly di ko pa personally natry kaya dapat tanungin mo talaga ang OB mo ulit or ask for a second opinion kasi may doctors na updated sa ganyan at iba ang approach, your OB's recommendation for betadine is also valid naman, it's what a lot of hospitals still use! A few of us moms prefer asking the hospital itself what they recommend or provide during delivery since they know best kung ano ang safe for postpartum care, lalo na fresh from labor. Better safe than sorry talaga especially pag first time mom ka pa lang, and since your OB isn't familiar with it, mas okay lang mag-stick sa proven methods muna while you heal.
