When my oldest DD (now 10) was about 4 or 5 she got a "life size" barbie from my parents for her birthday. You don't know how many times I came into the living room (I worked a 3AM to noon bakery shift) at 2am and had the living crap scared out of me.....I swear to god that thing looked just like a real little girl!!
Needless to say that barbie din't last very long in our house!!!
