You know how much I love songbooks, but I didn't find many board book versions when Juliet was a baby. I recently found some for Lucia and am looking forward to singing them with her!
Head, Shoulders, Knees and Toes
Ring Around the Rosie
Row, Row, Row Your Boat
These three songbooks illustrated by Annie Kubler are the ones I recently purchased. She has several others songbooks available as well.
This is one I did have with Juliet. We spent many happy afternoons listening to these songs together.
