I feel cheated... exclusively breastfeed on demand cosleeping, etc., ds one, AF back at 5 months, and he HATED the difference the hormones made to the taste of the milk, and we had a nursing strike every darn month when my period was due. DD, at about 9 months... I don't remember exactly, just that I was happy it was much later than with ds, and now, with ds2, I just had a period, and he's not even 4 mos. yet!
Funny, because my babies have all been big fat rolly-pollies from all the milk, too, and Reid, my youngest ds, is the fattest of them all, way off the weight charts, and so why AF?!
