When I was five in the middle of the 90s there were loads of nappy ad's on TV, it's most likely that back then nappies where newer and more exciting ergo something to 'shout about' ...there are hardly any nappy ads on TV these days. This is a mixture of three things: Capitalism is much worse and tailored, it's unlikely you'll see a nappy ad' during X Factor or during (better) event television, two TV is more careful slash woke, sticking with nappy ad's unless it's summer babies don't actually spend a lot of time in just a nappy (yep, blame pop' culture if you want to) and adverts these days in my opinion are not always misleading ...the second part of that is the panic crew's work, cloth the babies in associated ad's AND STOP THE PEDOS HAVING FUN etc. etc.
Finally no surprise nappies are still damaging the planet and that's another reason they are not so popular ......I never encountered - in the 'field' of education - another ABDLI+ MY OWN AGE before becoming a legal adult, I went to a private secondary school mainly because my family had the money ...what an excuse!! But my school's attendance was quite small, at a push there where 200 of us ...now towards the end of the 2000s I reckon 1-in-100 kids was ABDLI+ ...yes my school was 200 strong but money does different things to emotions and rebellion ...bad luck may played a factor as well but ...I'll put it like this, being outed as homosexual etc. in a small school can ruin your week, being outed as an ABDLI+ participator would ruin a year and no one could deny that!
I mentioned homosexuals purely as an example there, I've (also) only been Bi since last summer and whether or not I've confirmed/mentioned my age on here I am older than 20.
___ Anyway in secondary school the school therapist - who I told (as in TOLD told) - said she had a friend whose adopted Daughter had regressed between the ages of 11 to 13, I've always felt sorry for this girl in question as this therapist did not really spare her ...or at least this therapist confirmed to me that this girl had gone the whole hog: Wet and messy nappies (with mother-daughter changes for both)(I never actually checked but I'm guessing disposables), bathing (ditto), afternoon naps during the summer and being spoon-fed both types of food (if that's understandable). I was told when puberty kicked in with a vengeance she completely quit.
There was quite a bit of under-age-smoking at my secondary - it's one of the biggest ways rich kids go off the rails - and one girl did have a baby dummy of her key ring (some of the students night-boarded) to curb smoking ...looking back I've clearly been an idiot as she may well have been the other 1-in-100 ...I'll never know, I didn't like the school, it broke me away from established friends, was just for show really (damn my parents) and I say that as I exited it as I entered it NOT an academic (heyell no!!)!!!!!!!!!!
In terms of an answer to the question of the OP ...learning without the slightly dangerous internet (around the age of 15) that I was not alone (etc. etc.) added more lumber to the metaphorical fire ...making me the Infantilist I am today!!!!!!!!!!!!!!!!!!
