Psychology geek says "ooooohhh that's SO fascinating" - oh so sensitive about your suffering aren't I?

You've got what's called a 'conditioned aversion' - when 2 things have become negatively associated through repeated pairings.

It's pretty adaptive as it means that we learn to avoid things that have made us scared / sick / hurt. So, if you're bitten by a dog, your body will try to get you to run away next time you're near a dog - racing heart, adrenalin, flight response etc. Unfortunately it's not rational, just neurological connections, so obviously your body has decided that red pram and nausea are connected even though one did not cause the other. Funny creatures aren't we?!

Believe it or not, you can treat it. You just need to get yourself into a state where you feel relaxed and happy, and think about the pram. When you start to feel queezy, take long slow deep breaths and use your mind to try and settle your stomach. If you can master this thinking about the pram, do the same looking at a pic of it, or the pram itself. Alternatively, just look at or think about the pram regularly at times when you feel hungry and happy. You should be able to fairly quickly re-condition your mind that the pram is a perfectly safe thing! That is, if you can be bothered with all that to fix pram-aversion!!
