<human>: Can you give me a shortened version of the text?

My family has always done something on Thanksgiving day, Christmas Eve, and Christmas Morning. It's never just "let's get together and see what happens", it's been the same planned events every year. 

My husband's mom has never really done that. Her family isn't as intact as mine or really in to the holidays. When asked what her plans are she never has anything concrete to share and has just insisted on sticking with my parents stuff; she'd work around their traditions. 

My husband and I have a one year old. This has made her realize she wants the family traditions and all of the holiday activities to make memories with her grandson. 

How do I go about planning our holiday break when I have one family that has definite plans, and another that is wishy washy with plans?
<bot>: MIL has never done the holiday celebrations and has been fine yielding to my family's traditions. Has changed her mind this year. How do I split time without hurting feelings?
