I posted this in extended breastfeeding but maybe this is the better spot.

I've been bf for nearly a year now and I was wondering if bm changes in any way over the course of a year or thereafter? I've noticed over the last couple of months that my bm has an "oniony" smell and sometimes it makes my dd's breath stink for a few minutes! I've not changed my diet whatsoever and I HATE onions so I never eat anything with onions in it and my diet is generally bland, I'm not big on a lot of spiciness. So, I find this so odd. It doesn't bother my dd a bit though and there are no changes in her. I thought maybe something happens to the bm over time, not bad, just different. Seems like I've heard that it changes but I can't remember. Anyone know? TIA!
