We did Bigger last year with my son, and now this year with my daughter. Last year, I remember him having a harder time understanding the readings, so I'd add in little explanations to help him better understand the text. Now, this year, I'm having NO trouble whatsoever with my daughter understanding it. I think because I read these books last year to my son, it's familiar to me, and therefore I can add in voice inflection (raise and lower my voice, faster or slower depending on the events happening in the story). It works out really great and my daughter is getting SO into the stories. Last year it was unfamiliar to me, and now this year I kind of know what to expect, which helps. Maybe read ahead in the book, so you can dramatize a little bit which may help your child better understand and relate to the stories.
The Eggleston books aren't the only history books used through the year, as I'm sure you already know!

There's Journey's in Time, and the Wright Brothers and Their Sister, which are great books, too!

Hang in there, eventually you'll find your groove and things fill flow more smoothly. There are a lot of really great suggestions given so far, keep asking questions as this board is great for finding help or answers!
