One of the aspects of rectal temperature taking that appeals to me is the idea of the parent or caregiver's hand resting on my bottom, gently but firmly holding the thermometer in place. A lot of the instructions in child care books specifically say to hold the thermometer between two fingers and keep the hand on the buttocks for the whole time the temperature is being taken. There's something about the intimacy of that that feels exciting and embarrassing to me.
Do you remember having your grown-up's hand on your bottom, holding the thermometer in place, while your temperature was being taken as a child?
