4 hour time change with 10 mo old!

Hi! We are going from East Coast to Alaska this summer and my baby will be 10 months old. It is a four hour time change. This is a once in a lifetime opportunity for us because we have a friend that will be giving us a tour of a lot of the areas. I’m anxious about the time change and wondering if we made a mistake planning this trip with a baby 😭 any advice on the time change?! Or encouragement about the trip!
