I'm somewhat of a mix of 1980s and modern. I was a child of the '80s, so that holds a lot of nostalgia for me. At the same time, seeing pictures of me as an infant/toddler, the car seats, high chairs, and cribs nowadays are so much better. I prefer the plastic back used on diapers when I was that age but the modern prints and packaging are nicer looking. Google shows some cute designs from that time that I would probably like, but I only remember plain white diapers.
I prefer the cartoons that showed back then ('80s cartoons and reruns of cartoons from '60s and '70s) and don't really care for most modern cartoons save for a few Disney Junior shows like Sofia the First. I am somewhat of an electronics/computer nerd who likes modern tech but also has a strong nostalgia for the Atari 2600, Commodore 64, Apple IIe, old Macs and PCs, VCRs, etc...from the '80s and early '90s that I cut my teeth on.
I had this concept for a town just for Littles and their Bigs, AB-DLs, etc...which has different sections for different decades ('50s, '60s, '70s, '80s, '90s, and contemporary) with full immersion (minus the discrimination of course) where littles could live 24/7 as themselves. The stores would be period appropriate and sell furniture, clothing, and diapers sized for us in the infant/toddler/kids section.
