I'm right there with you all in the tiredness thing, and I can't imagine how I'd survive if I had other children now. You all are heroes! I always thought when people say "2nd trimester energy boost" that, somehow one got more energy than pre-pregnancy. Yeah right. At least it's more than first tri, when all I could do was sit o n the couch and stare at the wall, but still, pretty low energy. I feel really guilty about how little I do in a day. It's hard work making a person! And whenever I feel guilty and lazy, I remind myself that I'm busy making a new human. At least I'm doing *something*!
And I think too, in other times, the raising of children didn't just fall on the one and lonely mama. She would have had others around her to help pick up the slack while she was busy making baby. I hope so, at least, because otherwise, it's pure miracle that we exist.
