Took Offspring I to Latitude in 2016 (when she was 3) and then Camp Bestival in 2017, and took both of them to Latitude (Offspring II had his 3rd birthday while we were there) and Camp Bestival last summer. Plus done British Summertime/All Points East with them.
Has always been fine. Although slightly weather dependent - when the storm hit the final day of Camp Bestival last year it wasn’t quite so much fun.
Despite Camp Bestival being set up as a family festival, actually found Latitude the easiest as it has a specific family camping area away from the main campsites, which also takes you directly into the Enchanted Forest side of the main festival site. Looks like Green Man has family camping
We’ve got a five man tent that has a large awning area which is good for giving them a bit of space/stowing a load of crap/muddy clothes in. We’ve also got a festival trolley for transporting kit/sleeping children in - a pimped out version of one of these:
Every family with small kids seems to have one these days - I imagine it’s fucking annoying for childless festival goers, but there you are.
Bedtimes can get a bit fluid, as obviously headliners tend to finish around 11pm. Plus they have a tendency to wake up as soon as the sun hits the tent. That said, genuinely love taking our two to festivals - back to Latitude this year
