I know what you mean louise, if any of he kids are sick, i run fast in opposite direction and leave OH to deal with it.
If one of the kids looks pale or even retches my stomach turns over and i find any excuse to leave the room. I can cope with baby sick but proper stuff no way. Ppl taking about it gives me the cold sweats.
I wouldn't even go out on a Friday night as I couldn't cope with the drunks being sick. I get real panicky too, I can't cope with sound either, i turn tv up real loud. Gabriel was ill once, and he was in bed and i just knew he was gonna be sick i pushed him and OH into ensuite and literaaly ran downstairs into kitchen!
I was so worried about morning sickness but thankfully only queasy and controlled with ginger biscuits and cold bottled water. Like you I will do anything to try not to be sick.
I don't know why either louise, I remember when i was a kid at school, if someone was sick I wouldn't want to go the next day incase it happened again.
My OH doesn't really understand I just don't do sick, even on the tv.
