Same here, Fi. In fact, I was talking to Mum about it on Sunday and she said that she never owned a thermometer with 4 kids. She said you just know when the temp is too high. I am of the same mind... if I had a thermometer, I think it would make me a little paranoid and I would be checking all the time. In saying that, I bet I run out the door to buy one when Gabby gets really sick, LOL.
