Yaknow, if we go by photos, I'd say that I wasn't very liked :-) There are tons and tons and tons of photos of my brother as a baby, and a handful of me. One was a technology issue, the other was that - shall we say that I was rather homely looking, whereas my brother was all chubby and pink with curly hair? But, there might be something to it, that they were not there for a significant chunk of your baby-hood, and you more closely bonded to another mother figure, so you both had some level of ambivalence towards each other.
I have a quick question for you guys. Do you let your kids lick the bowl/spoon when you're baking, and the stuff has raw eggs in it? I do, and I sometimes feel like maybe I'm endangering her welfare or something. OTOH, I do it all the time, and don't feel at all like I'm taking a risk.
