Childrens Nighttime Drawing Journal - Each night have your child draw a picture of their favorite part of the day. Then write a caption about the picture. Would be a good "while making dinner" or "while doing the dishes" activity for the kids.
Have kids tell a short story this way. Tell them how many pictures they can have (min/max) and let them tell a story. - I love this idea so much!!! We all know how much kids like taking pictures of themselves :D
