I don't have an issue with Santa when they are little. At that age, they believe in a lot of things, magical creatures etc... and Santa is just one of them.
What I do have an issue with is the lengths people go to to ensure their children be,I've in Santa for as long as possible, way way longer than they believe in magical creatures etc..
Because to be able to do that, then yes you do need to deliberately lie to them rather than just telling them a nice story that they believe in iyswim.
I still can't get my head around the idea that an 11yo believes in Santa but knows that all other magical creatures, spells and what not are just make believe since they were 6 or 7yo. Especially because these children usually work that one out on their own. So why can't they work it out on their own with Santa unless we, adults, keep pushing it down their throat?
OP before taking that decision, I would look carefully at the whole picture. The joy of Christmas and believing in Santa. The pleasure and the magic of it. But also how let down some adults felt when they realised that adults kept lying to them about Santa when they discovered he wasn't real aged 10yo (if you look around on MN there are a few threads on that).
We did Santa in our house but from age 5~6yo, we never ever told them that Santa was real. If they ever asked the question, we just send the question back to them 'what do you think?'.
Dc1 knew when he was about 6 or 7yo.
Dc2 knew when he was a bit older, around 9~10yo but then he was also the same child who was still believing very Serioulsy in spells and magic until he was 8~9yo.
Both of them knew better than not going with the general belief that Santa was real (and TBH, I think they enjoyed this feeling of surprise and magic iyswim)
