When my son was born, everyone told me “They grow up so fast!” Looking at my sweet little baby, I thought that they were exaggerating. First, I waited for him to be old enough to get excited about Christmas and Santa. But, the years of holiday fun have passed quickly. He is only 8 years old and he and his friends are beginning to question whether Santa exists. Ahh, he is growing up too fast! What do you miss most as your children grow up?
