I’ve always been a huge fan of magazines and have read most of the ones mentioned so far. Earliest was Twinkle and I think Judy. Then SH, J17 and Mizz. I went through a phase of carrying around a copy of Cosmo as a young teen but it was really for show as fashion magazines are my least favourite. I liked Company, more! and also remember Minx as a favourite - it felt different.
As an adult I went off celebrity gossip and my guilty pleasure is now real-life magazines like Take a Break/That’s Life etc.
My DC love a magazine as a treat especially for a journey. DS has a Beano subscription and the occasional Lego mag and DD likes the Frozen/CBeebies type.
