My story is in direct contrast to the overarching themes in this project, but I'm adding it for another perspective.
I was fortunate enough to have an extremely supportive family and community, so I have encountered neither pressure nor moral outrage. Up until my mid-20's, I dreamed of having a baby and raising a clever, funny little feminist. But I have health issues and was worried about pregnancy. I considered adoption, but it seemed like an expensive and overwhelming process. That's when I realized that I was more interested in 'having a child' than 'being a parent'. Once the distinction was clear in my mind, I just knew it wasn't going to happen. Luckily, my family was very education- and career-driven and encouraged me to pursue my Ph.D. and an ambitious career.
I joked about "birthing" my dissertation- an expensive and laborious process. Now with my student debt, I couldn't afford a child anyway, but I'm increasingly happy and certain about my choice. I'm fortunate that in Los Angeles, I have a circle of childfree friends in their 30s and 40s, without whom I would probably feel very lonely. Other people may think I'm selfish, but I've had a handful of honest parents tell me that they love their children deeply, but envy my lifestyle.
The easiest part is my family–no pressure. My father's large family continues to multiply, but my mother's big family took a turn during her generation. With her generation, it became more important to provide a justification for why they DID want children and were ready for them. Half of her siblings had 1 or 2 children; the other half had none. I don't hear anything from my father's more traditional family. Maybe I get a get a pass because we moved out of the small town into very different lives and feel kind of foreign. Or maybe they judge me with the same standards, but are too polite to tell me about it.
The hardest part is finding a partner. I'm divorced and in my mid-30s. I'd like to get married again, and there are plenty of single men in my city who don't have kids, but many of them want to eventually. I make sure to drop it into the conversation by the 3rd date so I don't waste anyone's time. Thus, I go on a lot of 3rd dates. The most dangerous men are the ones who pretend to be OK with my decision but think I'll change my mind with enough time or love. I've ended two of those relationships already-- one of them I almost married, and one I actually did. –Marina
