As well, you can make it easier for your kids by incorporating a few things to the routine. You could speak to them about what they will do at school, who they might see, what time lunch is, anything that reinforces the security of the environment. Have them turn off their electronics before you let them out of the car so that they are not hearing their phone or iPad ringing or buzzing. This way when you pick them up after school, there are no electronic distractions which have been missing all day. Create an early morning routine with rituals, if possible pour yourself a coffee and enjoy talking to your kids before dropping them off to cut down the stress levels of the separation.
