The New Classroom and Adjusting

So...when there's a change in your child's life, how long is "normal" for adjusting to it? Levi was moved up the first of May. Since moving, he has cried. Every.single.morning. when I drop him off. What is wrong with my kid? For months upon months, he hadn't cried at drop off unless he was sick. He's not running a fever and doesn't have any abnormal complaints, so sick can't be the problem.

Is it normal for it to take a month or more to adjust? Is it just because the first week, he missed 3 days, then the 3rd week he missed 3 days (he was sick that time), and now, going into the first week of the new month, he had a 3-day weekend that was extended by one day on account of a doctor's appointment, making it a whole 4-day weekend? Sure, maybe that's all it is, and once we can settle into an actual "routine," he'll settle down. Right?
