Feeling Un-Motherly

PK is about 3.5 months old now, and though I carried her for nine months, gave birth to her, and care for her on a day-to-day basis, I still have trouble thinking of myself as a mom. Sure, I refer to myself as mommy in front of PK, but I don't FEEL like a mom. Far from it. Most days I feel like I'm playing house and that PK is my little toy. I know this sounds a bit weird, but I sometimes feel like I'm too young to be a mom. I'm 29, which doesn't exactly make me a spring chicken. When you consider, however, the fact that most girls get married in their late 20s and don't end up having kids until their 30s, that makes me a "young" mom. I'm sure I'll get over it and will ease into the role a bit more as time goes on. I guess that for me, a mom is a person who knows just the right things to say, gives great advice, is a good listener, and is a human shield, all in one. I guess I don't quite feel that way just yet. Maybe in due time!
