Families have different concerns about content for children. I encourage you to look uo individual shows on Common Sense Media or or the IMDB (Parent’s Guide section) for more detailed information.
A Charlie Brown Christmas
Rankin Bass Christmas specials (Rudolph, Frosty, Santa Clause is Coming to Town, The Year Without a Santa Clause, Twas the Night before Christmas, etc.) although some might be a bit “scary” for a sensitive child.
The Santa Clause (rated PG) if your family is relaxed and watches a lot of general movies together
How the Grinch Stole Christmas (also rated PG)
Here’s a more extensive list from Common Sense Media you night find helpful.
