I'm aware that formula is more fortified than breastmilk therefore we're meant to supplement but tbh imo you can't get better than a natural breastmilk and good quality diet- how many of you agree? Also, the flouride, my niece was given it, now has white stains on her teeth, my nephew wasn't, and doesn't. My sis is convinced it was a little overdose, as it were, as toothpaste contains it. We live in a soft water area though. How many of you don't give it? I'm just quite loathed to supplement- I feel it's a way out of trying to feed the bast possible, IYSWIM.
