I don't remember. I know I "knew" long before I admitted to anyone that I knew it was mom and dad. We kept it up for my brother, who is 8 years younger than me. Mum always used different paper for the pressies from Santa and the ones from everyone else. It was quite complicated at times, once I started helping her!

I was never too keen on sitting with Santa, but having him come down the chimney and in my house . . . goodness I never thought ot being afraid of that until reading this thread!
