Think sedatives should only ever be given if it's absolutely necessary and primarily for the childs benefit
Sure.
At 11 I was drugged up to the eyeballs with valium in order to get me physically into the dentist's (on the fifth attempt) to have essential work done. I had a similar experience to the phenergan, different, but similar. In the sense that I was trying to fight AND fight in a trippy way, but my body wouldn't respond. Terrifying. But they could bundle me in and do the work cos I was all floppy and couldn't go berserk like I had done in the previous attempts.
I get why they did it. Even though the memory is a far from happy one and contributes to my fear of any form of "not clear cut, properly functioning brain".
Speaking only from the perspective as a former child who was sedated, I would not be able to justify risking my child having a frightening experience, that they could not articulate once they came around, for the sake of something recreational as opposed to medically necessary.
I'm not having a pop at my parents. The doctor did the advising and the prescribing. And I have no doubt he thought he was doing his best for me as well as for them. But I didn't have the vocabulary to fully communicate how being drugged made me feel. And the post doping hangover exacerbated that. They just thought I had the odd, mild bad dream, making the trade off worth it.
It wasn't. Perhaps if it had been the single event, of valium to get me into the dentist's, I wouldn't have been left with a phobia of any medication that makes you fuzzy, or drowsy. I wouldn't get flashbacks at that moment as you drift off to sleep. Which jerk me back awake covered in sweat.
But it wasn't a one off. And I understand why. Having found something that controlled my stressed/anxious/bouncy response to events (and bedtime) my parents were seduced into seeing it as a solution that made their lives easier. Which meant they went beyond using it exclusively for times when they could have made a strong case for it being entirely for my own good.
