Flawed

I forget to cut my girls nails. Why? you ask. Well I don't ever cut my nails, I don't ever remember cutting my nails as a kid. So I do think to cut their nails either. Only when I see that Emma has scratched Isabel or vice-versa will it dawn on me that their nails may be too long. I've thought about setting a reminder in my palm pilot maybe every 2 weeks to remind myself to cut their nails. Does this make me a bad mom? Does anyone else a this same problem or something similar?
