How to say it?? Help??

Tiffany • Fri, Oct 24 2014 • I`m a mother of 3 children. My daughter Naomi (6), my son Elijah (4)and my younger son Asher (2). I`m not married. I hold a healthy friendship with their dads.

I want another child but I don't know how to tell my boyfriend without him getting upset or scared. What should I do???
