teach2183, yes I'm planning to breastfeed, but am not sure about relying on that to not get preggo again. Good point about avoiding hormones while still breastfeeding - that's something I'd rather not feed my kid. Perhaps I should think again about the copper one or use another method until little guy is onto full solid foods.
Thanks Sihana & halfbunny for your responses too - It seems the experience is totally different for everyone, and I may just need to wait and see how these work for me.
Geez - now if only I could get my bread-loving boyfriend to consider going primal, even a little. He loves when I cook something like spinach-stuffed chicken wrapped in bacon (with potatoes), but he prefers most of his food in sandwich or burrito form. No talking him out of it.
