I picked up two packets in the chemist, one said 'not recommended if lactating' and the other didn't mention it. My googling skills all go to links about not taking it during pregnancy, nothing about lactating. Even kellymom doesn't tell me much.
I only breastfeed my 16-mo-old once per 24 hours now, so I'm really reluctant to hold off unless there's a compelling reason. And even then, I'd be tempted to wean instead.
Can anyone tell me if it's okay to take SJW?
