Ultimately, those who have only known smaller families - where you and your entire family you've ever known have had the stereotypical-ish 2-3 kids or less - may struggle a bit with keeping up with the fairly large family and the dynamics therein. But work with it, because most everyone gets their chance to be a mostly-realized age-appropriate actual person... even as most of the actual action really does focus on the more senior people. (In other words, even the toddlers get a chance to be toddlers, but the teens and adults ultimately drive the story.)
Truly a great work, and a Toby Keith level master class in "I can spin off a story about anything". (Look up the story of TK's "Red Solo Cup" to understand that reference. ;) )
Very much recommended.
