My son has his routine down pat, since we try not to mess with it. Leaving it the same day to day causes less meltdowns. Knowing this week will be tough we have been practicing where he is going, who is picking him up, and where i will be. Tonight he himself put his winter gear in his bag, just in case. He also made sure that he had his comfort items exactly where he'll find them tomorrow. I have probably answered the same questions dozens of times but I think he will truly be fine.
