You need to make a list of what you are spending that money on so you can really see what you have spare per month.
From an outsiders perspective my girls have great experiences. We go on lots of days out, they have nice clothes, get spoilt at birthdays/Christmas, house is as nice as a rental property can be.
However, our food budget is super low - cook from scratch, use yellow labels, cook vegetarian, use olio where possible. I only spent £250 per month for all food, toiletries; cleaning and cat food.
I spend my time finding good deals on days out or planning train Fare far in advance to make use of cheaper fares.
Days out we take a picnic, hot drink in a flask. May occasionally buy an ice cream or something. But rarely eat out except special occasions.
Clothes are bought from vinted and charity shops. Or from olio.
Presents are often second hand, on offer. I use cashback sites etc.
I dont buy anything outside of birthday/Christmas. No random magazine, books, toys, things from gift shops. In fact I only buy things that are essential.
I sell on anything no longer being used. Dds needed a new tablet each for school work. They sold lots of their outgrown toys, clothes and computer games to fund them.
Me and DH earn minimum wage so have nowhere near £800 spare but I know I want to prioritise experiences so I cut other areas to make that happen.
