It is great to live where breastfeeding is more accepted. It is actually specifically illegal in Hawaii to try to stop a woman from breastfeeding in public. There is something very relaxing about knowing that. I am all for enacting similar legislation in other States. I've seen too many women who feel the need to nurse in the bathroom.
I'd love to see more knowledge about breastfeeding in general. I've had some of the most magnificently ignorant things said to me, and more to the point I started being met with utter disbelief when I was still nursing my oldest at only
four months. (Not that they thought it was a bad thing, just that they saw it so seldom.)
Of course, I've nursed everywhere I've been.
The best thing I can say for breastfeeding and immune system is this: my nurslings tend to not get sick even when I do. And I co-sleep. Which means there is a
lot of contact.
