My sons are 6.5 years apart in age. My oldest one realized Santa was not Santa when he was about 10. I wanted to keep the magic alive for my 3 year old son, so I told the older one that as long as he kept his mouth shut, Santa would keep bringing HIM presents every year, too. Miraculously, it worked. It was my freaking mother-in-law that spoiled it for my younger son!!! When he was about 6 or 7, she said to him "You don't still believe in Santa, do you?" I could have KILLED her. He was so sweet and innocent and believed in anything magical, and I really wanted to keep it that way for as long as I could.
The youngest kids in a family always have the shortest childhoods. 😞😞😞
