Bookworm's interest at under 12 months: He always enjoyed seeing the babies.
"Crayons are quiet./Pots and pans are loud. BOOM BAM"
Bookworm's interest at 14 months: The bookworm seems to quite like it. Sometimes the cover will make him shake his head "no," but if I open the book up, he then wants to read it. I should try this again (at 21 months) now that he fully understands the concepts of quiet and loud.
Bookworm's interest at 13 months: This was too advanced for his age at the time we read it (13 months). He'd often bring it to me to read him, so he must have really liked the cover, but he wouldn't last more than a few pages. I might give this one another try soon.
