Sometimes things don't work out the way you'd planned. I always wanted at least five kids.
I had one child for nine years. I remarried, though, and wanted a child with him. Once the second was born, we decided to try for a little brother or sister, so she'd have companionship. My eldest always felt she got gypped out of a little brother or sister. I have three, and that's just right for me.
I've had some ask me why I decided to have "so many" kids. But then again, I don't put much stock in what anyone's random comments, unless it's a constructive criticism or sage advice. Replacement kids? What an ass.
What I can't stand, though, is when they insist that my younger girls look like twins.

One is fair skinned, slightly wavy lighter hair. The other has dark skin, very curly and kinky. Facial features are completely different.

The only similarity is that they both wear glasses and have braces. I think sometimes people say ludicrous things when they have nothing to say.
