I managed to help my family have Family Home Evening 26 times this year. We are busy people and we do a lot of things together already, but it was important to me to have an actual Family Home Evening every other week at least. We focused most of our lessons or messages on things that Jackson could understand so he felt included.
This is how we've decided to structure our FHEs:
Opening song (usually a song out of the Children's Songbook)
Opening prayer
Fun song (Old MacDonald, Dinosaur song, Itsy Bitsy Spider, etc.)
Family Business
Lesson or Message
Closing song (usually another Children's Songbook song)
Closing prayer
It seems like a lot but we don't usually take longer than 15 minutes. It's the perfect length for Jackson's active mind. Jackson even helps us with the prayers sometimes. :)
I will definitely be including another FHE goal for my 27 Things this next year!
