As the school I work at has seven preschool classes as well as four classes of each of Kindergarten to Year 2, there is always a need at some time for books that address the worries that go with being separated from a parent while at school. Most teachers have their favourite 'go to' book for this purpose, but it is always good to have a few more at hand in case the specific one they want is on loan at the time. If you're a parent you might like to adopt the Willa Perlman idea of kisses in your pocket from the book
Pocket Kisses.

At one stage this was very popular in our preschool, but the library copy of the book fell apart and hasn't been replaced. Just looking though, I see that it is still available.
Separation anxiety is a normal rite of passage for young children. It is common at drop-off time, but can occur anytime and with even the sturdiest of children on a 'bad' day. Picture books enable adults to address the angst of separation with humour and warmth and as many of them feature animals, there is a distance from the child which means they can smile at the animal's quandary. Most children just need reassurance that their parent will return to pick them up.
Below are some books from our library that I have recommended over the years. The beginning titles are usually all that is needed to reassure students that their parent will return. Often I send the book accompanied by a plush toy that accompanies the book so that the child has something to hold while the story is read and discussed.
