This is a term I'd never heard used in general conversation before joining mumsnet, but since I've joined I've seen it pop up everywhere.
It's often used in the context of giving teens more freedom (e.g. 'DD needs to learn to self-regulate her screen time'). Sometimes I come across it in threads related to adults ('DH can't self-regulate his drinking'). The latter makes me laugh.
In both contexts, I find the term extremely demeaning.
If you'd have asked me last year to take a stab at who needs to learn to 'self-regulate,' I'd have said very young children who haven't yet learnt they will be sick if they eat too much.
To stick with the example of a teen who has been up all night on their phone and is now tired - team 'self-regulate' would jump in with 'they need to learn to self-regulate their use of their phone' or the more sinister 'they have proved they cannot self-regulate - take it off them'.
The issue I have with this example is the amount of phone use that is considered the 'right' amount is set by the parent. This amount is usually the amount required not to be tired the next day for school. Obviously this comes from a good place.
However, using the term in this context completely takes agency away from the teen. It assumes a default position of the parent's view of the world being 'correct' i.e. the unequivocal 'best' thing for the teen is for them to get some sleep and wake up bright eyed and bushy tailed for school.
I agree that teens do need some guidance here, but when I hear that 15 year olds apparently can't 'self-regulate' because they use their phones at night, it gets my hackles up. They are making their own decisions around what they want to do, just because it deviates from what you want them to do doesn't mean they can't 'self-regulate'.
Going to go out on a limb and say the best thing for a teen isn't always being wide awake in the morning. If they're having a hard time, for example, they can find an awful lot of solace in late night conversations with friends, sharing heartfelt feelings that just wouldn't come up in daytime chit chat. Could really help their mental health. Personally, I stayed up playing with the HTML of my MySpace page and now make a very good wage in an IT role. IT in school was crap and I wouldn't have developed an interest in it from that. I know that's a personal example, but you know, just saying. What's 'best' for your teen isn't always that clear cut.
To put it another way, sometimes I find myself on mumsnet at 2am when I have work in the morning. Is this demonstrative of my inability to 'self-regulate'? What about when I have an extra bag of crisps? Or go on a Netflix binge? Do I need someone to step in because I clearly can't self-regulate? I'd be rather annoyed if they did. In fact, if someone I lived with took the crisps out of my hands or took my laptop off me 'for my own good' I would consider that abuse.
I'm a grown woman, but to me that doesn't give me additional 'rights' over a teen. And if someone told me I couldn't 'self-regulate' (or made this clear in their actions) I would be offended and feel infantilised. I might even believe them.
Just some thoughts... (:
