We are big on the magic and were devastated when Emmy at 7 found our stash hidden away in our walk in robe under a bunch of clothing so we had to be creative by sorting some that we had to give the kids from us, and then we used cellophane and ribbons to bunch others together to make them look different to the ones she had seen. It worked a treat and she believed up until last year..11!!! Best of luck, it can be so upsetting, but its in the way that you handle it..and after I in true infant style also, yelled at my 7 year old for snooping, I knew that I had to try and be creative somehow...the magic and imagination is just too important.

Goodluck, i feel for you.
