Goodness! For the record, throwing up is also a HUGE phobia of mine. I have a daughter who gets carsick, and I hesitate to even take her to the park if her dad isn't with us... it's horrible. You're one step above me though... I can't even say the V word.<br><br>
Anyway, my suggestion (as horrible as it might be) is to ignore the behavior. At 11 months old, she's probably quite aware that this behavior gets a reaction out of you and enjoys getting what she wants by doing it (you take her out of the high chair to clean her off, remove her from the bed to change the sheets, etc).<br><br>
When our daughter gets carsick, we used to remove her from the seat to clean up. Soon a negative association was made with the car. She would anticipate it, fight getting in (then fight to get back out when she does throw up) and scream the WHOLE drive. There was even a point where I thought she might be making it happen just so we'd stop the car and let her out. Once we started to not make a big deal out of it (we would just say "Oh, yucky! You threw up! Let's get you cleaned up so we can keep going", but not remove her from the seat and then keep on driving - we can clean up better later), leaving the house because much less of a big deal. Now when she gets sick, she shows us her hands, says "ucky", and we clean her up and off we go. She still fights to be put in the carseat, but once she's in, she's fine.<br><br>
I'm not really too sure what else to suggest to you. Don't make a big deal out of it, clean her up as best you can without giving her what she wants (or keep little containers near by she she doesn't make a mess), and she'll soon learn that this behavior isn't going to get her a reaction.<br><br>
I'd love to hear what others say about this. I'm sure there's a better way, but it's such a phobia of mine that I honestly don't know how to deal with it in any other way than by use of extinction. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/greensad.gif" style="border:0px solid;" title="greensad">
