It could be a short-term phase. I yearned for children in my early 20s. I got married at 22. I eventually stopped thinking about children. Then I started wondering again, and I was pregnant at 28. The second one came soon after. We may or may not be done. We'll see. I'm not much of a long-term planner, but most things work out for me. You don't have to yearn. You're either meant for it or not. I believe in fate.
