Hello Tom,
Welcome to the Disney Parks Moms Panel. There is nothing better than planning a family visit to the Walt Disney World Resort.
Your daughter will have to sign in to
My Disney Experience, and in My Account select Family and Friends List. She will have to click on Add a Guest, and then select "I’ll enter their name and age". After she fills out Guest information, she will have to select that she will be managing their plans.
If your wife has a Disney Account, you can all get connected and then when you have your tickets make sure they are all in one account. I understand they will be your daughter’s responsibility and she will then make
FastPass+ selections for the family. When you make selections, you can choose all family members you are making that selection for.
I hope this helps you while planning. Please come back with more questions.
Best magical wishes,
Thiana
