My son was studying am full day nursery and now studying pm class. I and my son like the PM class more as no need to wake up so early.
The transition period only take me less than 1 week.
Your son wake up that early as he can have afternoon nap. If you can get rid of the afternoon nap, he will wake up a bit later.
For example, my son used to wake up at 8am when studying at nursery. When he joined the pm class, he wake up before 9:00am and need to have afternoon nap after going home. On day 5 (when joining Precious Blood), I brough him to a class instead of going home. Thus, he did not take the nap. And you and he will find that it is OK without the nap. Since day 6, he woke up after 10:00am and don't require the afternoon nap.
I prefer PM class as less students but with same amount of teacher. The ratio of Teacher : Student is better.
One more thing to share why I choose the pm class. My husband usually come home later that after 8:30pm. If we choose am class, we may not have much quality and quantity time with my son as he may need to sleep very earlier. Now we can have hours of time playing together
One thing about the reading program, it is very very succesfully. My son need me to read books with him before going to sleep. Even I am super-tired, I still have to do so.
