hehehe, Morgan I am 25
I don't know if this feeling will ever go away. My close friend is 9 months pregnant and she too did not want kids, but it happened (she's been with her partner for 10 years now) My mom is a single parent and I know what you mean I so respect her strength. And you sound like an amazing mommy to Isaiah (that's him in your avator right? he's so cute!)
I use to want babies and wedding and all, but the more I mature, the less I want such things (I have just "helped raise" too many children, as I am one of the elder youths in my family)
I think I'm going to stick to spoiling my baby cousins (I have 6 of them so you can imagine!!!) and soon to be little "nephew"
