Help! New nursery drop-off clinginess for 3 yr-old (also poss adhd/asd)

[Neurobubble]

Hello!
My daughter has been at nursery a couple years and after a tough time settling in, and moving rooms, she thrived.
Recently though she started wanting me to come in to the room for a bit in mornings. nursery were fine about this at first but have now said we need to get back soon to drop offs at the door.
When I’ve tried that recently she was hysterical. Apparently she calmed down in the room and I guess the theory is she’d get used to it…
I’m worried about it affecting her tho - she has some other neurodivergent signs (I’m also ND) even though she is generally a really happy child and I guess I’m wondering if she needs something different.
I feel a bit stuck in a loop too - ie they see this clinginess as unusual/a problem but not necessarily another sign of neurodivergence. I’ve only just started these conversations about possible ND with them based partly on her last report as well as how she is generally, and I’m not sure it resonates with all the staff.
anyone else had any similar experiences with new clinginess?

Have you spoken to the SENCO? What support is the nursery providing? Have you tried an item DD can keep with her or some draw a little heart on the child’s hand?

If you believe DD is ND, have you looked at a referral?

If her clinginess is linked to her possible neurodivergence, it may be that something about the nursery setting is making her anxious. In which case, you staying in the room isn't going to help address the actual problem.

Have you tried a visual timetable of the morning routine, with "mummy leaving" as an item? Would it help your daughter to know exactly what the first activity will be when she goes in?

A lot of children in my son's class went through a clingy phase around age 3 - in part, I think, due to a better understanding that staying with parents could be an option, and a more of a sense of mummy and daddy being somewhere else, or friends being at home that day. So even if she is ND, the clingy phase might not be to do with that.
