The vom scene confused me too - perhaps she was still drunk from night before? I just thought it looked like she had morning sickness!
Actually, I found it quite disturbing from the point of view of the kids acting - my DD2 models (OK, hurl the bricks at me now ) and so far she has done "nice" stuff like clothes and toys - when I see little kids in commercials I wonder what I would do if I got called to make her do a scene where she screamed at a cot (even if it was empty as I presume they didn't really make the girl scream at a baby!), or stuck the finger up at someone, or one of those NSPCC ads. I don't think I could let her do it - the money isn't worth putting unnecessary thoughts in her mind (God knows, she's imaginative enough as it is!)
Made me think also of the little things we do that they see and pick up - the times when you are at the end of your tether and you are asking the kids to get out of your way, or being really snappy. Hmm, food for thought.
