I lived in a small town where enemas were given as common as giving aspirin. On many occasions I would be playing my friends bedroom when her mom would lead her sister into the bathroom where a bulb syringe was waiting. I could also hear the child complaining or crying as the enema was administered.
On a couple of occasions I actually saw first hand the enema administered. The first time my best friend Patty and I were going to her house after school to ask her mom if we could go looking around for clothes at a local store. When we entered her house her mom was in the nursery attending to her baby brother. When we walked the room her brother was on top of the changing table lying on his back and legs geld up by his ankles while Patty's mom held a rectal thermometer in her bother's fanny. Patty started to ask her mom if we could go to the store when the thermometer was removed, Patty's mom said that we could go but first watch her brother while she prepared an enema.
The second enema I saw when my cousin Pam and me were going to study in her bedroom on day after school. As we were passing her parents bedroom the door was open and we saw the neighbor lady laying on her side on the bed as Pam's mom squeezed the contents of the bulb into the neighbor. Pam and I quietly went to her bedroom as her mom gave the enema. After 20 minutes or so we could hear the neighbor expelling the enema in the bathroom.
