Mak,
The joys of the working mum! I totally hear you! My DS just started school too and we are having similar issues with not wanting to go to school. We had similar issues with Kinder and we have a big whiteboard which we made together running through exctly what happens each day. I'm a Prep teacher too (on leave) and I use this with my new Preppies. Break the day into 6 or 7 manageable parts (drop off, literacy, snack, maths, sport, lunch, library, afterschool care) so at the beginning of every day she can have a look and see how many things until she sees you again. Occasionally I give kids a little bookmark they can keep in their pocket with picture cues so they can always see how many things till they go home.

It helps my DS, it might work with your DD. A special toy or activity to do at afterschool might help too, as security and incentive.

HTH, good luck
Bec
