"Perhaps, her pregnancy was not that "unplanned" but subconsciously planned due to her cultural upbringing of how women are to be mothers."
My stepmother was 36 when she had my half-brother, and if he had come along earlier (5 years or so), it wouldn't have been as much of a shock. I was already out of the house, and had been for more than 3 years when she found out (I was a senior in college when this happened last fall, and I'm now in a Master's program), and my brother had less than 2 years of h.s. left and he would have been gone. My dad is 10 years older than my stepmother, and it's bad enough that he has a physically demanding and potentially dangerous job (he's in home improvement), but he doesn't have a retirement fund or even health insurance. One of the only times I've truly been upset, angry, and ashamed of my dad was when he told me my stepmother had caught pregnancy. He told me over the phone (knowing full well how I feel about kids, his lack of a retirement plan, and the fact that it was hard enough being closer to a stepmother than my biological mother, even without her having any kids she gave birth to), and was an ass about the whole thing...like, "Oh, I'm 45 and my dick still works!" My stepmother was considerably shocked by the news (she thought she couldn't catch pregnancy), and even upset, because she and my dad were so close to being empty-nesters. She's wonderful with kids, and not just us...being a Latin immigrant with only a h.s. diploma, she held a slew of babysitting and daycare jobs (including running a daycare out of our house when I was in h.s.); we met her when she was the nanny for my best friend's family. And to her credit, she worried so much about my reaction...once, we were hanging out and she (jokingly) told me she was pregnant. I told her that if she ever did get pregnant, I'd never visit them again. Of course, I was speaking hypothetically, never guessing that she would have a kid. After we talked about it, we were on better terms...I was the only person throughout her entire pregnancy to see through her condition enough to ask her how SHE was feeling, rather than exclaiming about her uterus working. And she's been pretty sensitive with regards to me and my lack of interest in all things kid...she left him at home with her sister for my wedding (which was 5 weeks after he was born), and when she came to visit my husband and I in our new apartment, she also left him at home. And oh thank heavens, she uses a breast pump behind a closed door, rather than letting it all hang out in public. She doesn't have as much time for me now, but since I live 85 miles away, that's to be expected. They're coming to our place for Thanksgiving, and she'll be bringing the baby, but I expect he'll sleep most of the time...I asked her to bring a blanket for him so we can spread it out on our bed and let him sleep in our room. My dad doesn't understand my position like my stepmother does, and so has gotten angry with me because when I talk to them, I don't ask about the baby. It's not a malicious thing, it's just that I don't think about it...and I don't want to think about it. My parents work hard, and watching them miss out on good things because they weren't more careful (and refused to exercise their right to an abortion...they live in a solidly blue state and there's a Planned Parenthood clinic not 35 miles away from them) is going to be difficult. My stepmother is very intelligent, and was only a few credits away from an Associate's degree, which would have lead to a B.A. and a good job (she wanted to be a high school or middle school Spanish teacher). And my dad is 46 years old...I worry about him climbing around on roofs and ladders, and crawling around on his hands and knees (a knee injury landed him in the hospital for a week a few years ago). It's hard, you know?
