First, why does anyone think this is okay to ask? I think I asked my dear friend R once - but she's one of my closest friends and we've known each other for fifteen years. Also, she had pre-eclampsia both times and I was afraid someone might, God forbid, die a third time. Aside from that, I may wonder, but I sure as hell don't ask.
Will I have another child? (I am fortunate enough to have no fertility issues that might prevent this; it's pretty much just up to me.) Probably not. A year ago, I would have said maybe. After the last six months of Continuous Bug Meltdown (he tried to head-butt me this week! And he slapped me across the face!), and after a year and a half of what I could only characterize as pregnancy/breastfeeding-related poor health*, I'm honestly not sure I'm willing to go through any part of that again. It would be very hard on my spouse, and I would be not-really-there for the children, and... well, I'm never taking that many antibiotics again unless the alternative is death or serious injury.
It seems ridiculous to put us all through that again, when I already have two healthy children and, more to the point, no burning desire for a third.
* In pregnancy: Migraines, 30 weeks of nausea, and strange sparkly visual stuff. Afterwards: mastitis, more migraines from antibiotics, chronic sinus infections eventually requiring surgery, more mastitis, FUCKING THRUSH, and, oh yes, the ridiculous food-allergy stuff probably resulting from all the antibiotics. This all happened the first time too.
