My mom is looking for a book, but doesn’t know the name of it. Here’s what it’s about:

Okay, so the book that my mom is searching for is a Christmas book that's about spoiled kids that were upset that they didn't have video games or internet and they were mad and they went to the grandparents farm and they didn't have any TV and parents had to work. one person took a plane the other took a car and met up at the grandparents house for Christmas. It also has a seal of approval she says.

We both have searched Google and nothing has come up. I know there are probably a thousand and one Christmas books like this but if you know it, please help. She's been looking for this book for nearly 35 years
