My 3yo has a really hard time with the transition of going into preschool in the morning. We have a morning routine, he gets ready fine, helps pack his bag, and speaks positively about what he will do today at preschool. Literally at the door, he breaks down in tears and says "I want to stay with you", with floods of tears and usually screaming. He's fine at preschool once he has calmed down, and at pickup time he is always happy and tells me about all the things he's done today and who he played with.
I'm not sure what to do to help him. Preschool isn't a new thing, he's been in nursery since he was 6 months. I've never lingered at the door (he was a COVID baby so I never even set foot in his previous nursery, just handed over at the door). He had issues with the transition going into the previous nursery too from about 18 months, despite absolutely adoring his caregiver.
So: the problem isn't the preschool. He likes it there once he's in and calmed down, he likes the staff, he has friends, and I'm happy with it (and changing wouldn't be an option - it's a government preschool which is free where we live, and private would not be financially possible).
I don't think the problem is particularly our morning routine - he's positive about preparing for preschool when we're at home.
It's also not about some kind of general anxiety about me not being around: he doesn't mind being left with trusted friends, even overnight, and he's not unusually clingy.
He's very articulate about his feelings, and will tell me "I don't want to cry today" or "I was crying this morning because I wanted to stay at home with you".
It's really about that moment of transition. A couple of weeks ago he managed to go in with no fuss at all for a whole week when he decided exactly what he was going to do when he got inside: he was going to run straight to the "tea and biscuits" table. But then he was home sick for a day and it all started again, and the tea and biscuits solution seems not to be working any more.
Any ideas about how your kids got over this? (I'm a single mum so there's no option of someone else taking him to preschool).
