With a new baby due in a matter of weeks, I have really been in the nesting mood. Not only cleaning, but getting everything all lined up! Today, I found the black and white images that I had used with C. I loved these visual stimulation cards and recommended them often to new parents when I worked as a parent educator. The black and white pictures shown are from http://www.funbabygames.com/, also check out these black and white images, they are free to print.
There are also some great black and white board books that I just love. Tana Hoban created these books and they are most likely available in your local library. These books are great to 'read' with baby or prop up during tummy time.
