I am separating this question from my other one about immune disorders because they're not completely related, BUT I was stunned and dismayed when my period came back suddenly yesterday. I have 25-month-old twins, and I know it's been a while now, but I thought as often as they nurse (many many times a day) and their being 2 of them, and they don't drink any other kind of milk, it shouldn't be back yet. Could this be some sort of indicator that for some reason they aren't getting enough milk? If you saw my earlier post you know I'm worried that one of them has something wrong with his immune system and I'm freaked out now that he's not getting enough breastmilk either. Sorry to sound like melodramatic, but there it is. I sure would appreciate any reassurance you can give, or honestly if you think there is a problem.
