Will any grandparents, pets or extended family be joining?
Do you go out on adventure? Do you stay home and play boardgames? What do you enjoy together the most?

All the siblings, mom and dad alone, generational photo, etc.?
I'll have my checklist of shots but you may have a specific idea or something meaningful to include that I wouldn't think of!
Nap/bed times, sensory sensitivities, mobility limitations, etc.?
