K.S.
I just started reading chapter books to my two sons at bedtime too. They love it and so do I! I have only read two so far and they were Huck Fin and Tom Sawyer books. But not the original version... someone gave me condensed children's versions (with out the "N" word and stuff) that are 6 short chapters each. I haven't thought about what to do next... My little brother use to read the boxcar children books. THey are short but chapters...maybe those will be good.
Besides chapter books, you could read poetry for kids. Like Shel Silverstein.. all of his books are good and have funny nonsense poems in them. My boys love those so some nights we read several pages out of one of his books ( I have all of them!). Anyway, good luck!
