How was the transition? My 19 month old is starting part time next week and I'm expecting drama but I don't know in what capacity. Will it affect his nighttime sleep? How long should I endure the crying before I investigate whether the problem is the daycare center? Any tips on making it easier? I let him watch the Daniel Tiger school episode where the theme is "Grown ups come back" a couple times a week and I talk to him about how fun school will be but I'm not sure he understands. TIA!
