My DS1 (6) told me earlier this year he knows Santa isn't real, but today we got a toy catalogue and I told DS2 (4) it was from Santa to help kids write their lists I was just about to whisper to DS1 to not ruin the magic (because I thought he'd stopped believing) when he suddenly became quite excited about Santa knowing where we live (we moved this year).
I almost feel a bit worried because I don't think I did believe at age 6?
Are his friends going to mock him for this?
When do they stop believing?
