I was almost always laid over my mom or dad’s lap for rectal temperature. My fondest memories of mom doing it was in the bathroom….she would sit on the toilet and have my sister and I bend over her lap. Dad would sit in the rocking chair in the living room on sit on the side of the bed and put us across his lap! Suppositories were given in the same position! Sometimes mom would have us lay in the floor in the diaper position but that was kind of rare.
At the doctors office visits sometimes we laid across one of our parents laps or we laid face down on the exam table!
Now as an adult I like to lay across my husbands lap and at sick Dr visits I lay on the exam table or they have me just lean over the exam table!
