Hey mama, don't worry, a Brazilian treatment shouldn't affect your breastmilk at all, kaya no need to stop! A few of us in my mum group have done it while breastfeeding and our babies were totally fine, pero since it's a health thing that's making you anxious, mas okay lang magcheck with your OB just to put your mind at ease, lalo na kasi different products ang ginagamit. You're doing great at 6 months of breastfeeding!
