I'm turning 27 next month and I have absolutely no desire to have children. If it happens, i'll be happy, but if it doesn't happen, I'll be happier.
also i think my 20's and even early 30's .. i'm still a kid.. my husband's younger than me so .. he's still a kid. Ideally if it was to happen I'd love for it to happen when I'm like.. closer to 35. Because then I can relive all those youthful things when I no longer feel like a kid myself.
but then again, who knows, maybe i'll still feel like a kid at 35
