Parent-child parking spaces at supermarkets should be reserved primarily for those with children aged 5 and under, aside from older children with special needs (although a blue badge might be more appropriate where they meet the criteria, in these cases).
I was alone with my 4 month old today, the trolleys with the baby seats are kept next to these spaces. The spaces which have the easiest access to the trolleys had all been taken with the last taken by someone just before me, I reversed into a space around the corner and the driver was shaking their head at me, presumedly because their space only had extra room on one side and my space came up to them (see picture). I was surprised to then see them get out with a child of about 13. I saw multiple other people using these spaces with children looking like teenagers. I was able to get a space which still had fairly easy access to the trolleys, albeit by needing to walk on the road and inbetween the other cars, multiple people had parked in the spaces with the easiest access with much older children. I was lucky to get a space at all, had I not I would have had to walk across the busy carpark holding my baby.
YANBU- Just because someone has a child under 16 doesn’t mean they should take up these spaces, they should save them for people who need them the most.
YABU- first come first served, who cares if someone with a baby is having to traipse across a busy car park holding a baby to get to the baby trolleys.
