Parents, this is for you: When did your children stop believing in Santa? And how did they find out? I'm a big Santa person, but lately my oldest daughter, who is 8 and in the third grade, has been doubting. Today, on the ride home, she was kinda talking to herself, and I heard her say "That's how I can prove it!" So I ask what she's talking about, and she tells me she has a plan for finding out, but she won't tell me. Of course, I pull out the "he's real if you believe he's real", but she looks at me like . She is a very down to earth, proof-is-in-the-pudding kind of kid, so I'm worried this could be it. Another problem-we also have a 4 year old. How do I handle that? Older dd is not mean intentionally, but she is very into the truth, laying it on the line, and not mincing words. She won't be into keeping it a secret for her sister. Advice?
