Is ten years old too young??

Lededra D • Hey, I am 26 years of age. Me and my better half have being trying to Concieve for 6 years. Hopefully we'll be able to get our little blessing.

I want to get my step daughter a promise ring. But idk if I should do it now or wait until she's 13. I feel like right now is too soon to explain saving herself until marriage. But I also am scared that if I take too long others will influence her.
