why I only have one kid period. LOL. No, I just always wanted just the one (I grew up as an only child too). My mom had me just shy of 40 years of age... in 1971. But, she looked tons younger. My dad was almost 44. So, I get it! Heck, I felt young at 35 having my son.
Funny story -- I have a high school classmate who had a baby in her teens, 20s, 30s, AND 40s. I teased her with her last one, "what are you going to do in your 50s?!?!?" She laughed and said she was DONE. Well, she just announced at 51, she's having twin grandbabies. Well, that's one way to do it! LOL
