Where can I find a printable pictures/ drawings, which is needed to hang up in front of a baby for watching?

Search under images for Graphics or be specific like Baby Graphics and you can save and print from there. You could also make your own with cards and a thick marker to draw simple shapes like hearts, circles, squares and spirals. Simple bold image stimulate and amuse children from 2wks - 4mos in most cases then should be updated to colorful animal and character images. The best images are family and friends smiling and even pictures of the child with them. A Mylar mirror is great from birth to age 5 since children love to look at themselves and it instills a sense of safety and well being. Don't forget that Brahms, Beethoven, Chopin and other clics are excellent for encouraging math sense and increasing dual language capability.Good Luck!
