my toddler went to Pg but we started him off half day first. 9-12pm. then gradually 9-3pm , after about 3 weeks then we sent him 9-5pm. he had a terrible meltdown as it was a sudden change going to school and all but after a while he got used to it. now he's in N1 and still cries occasionally esp during routine checks but settled down once in class🤣 my tip is not to linger around after dropping off , just tell toddler you'll see them at the timing you're fetching them and if you're gonna be late , just let them know so they won't wonder why mummy/daddy is late. hope this helps!
trust that in time you will both adapt. have lots of hugs together at the start and end of the day. keep drop off prompt and don’t linger around.
