Thing 1: Approach your local kinders (try ringing the day before they re-open) to ask whether they have any new vacancies. Ask to speak to the manager/person who handles the enrollments. Explain your circumstance (just moved, DS very ready for kinder, etc) and if they still don't have a spot, ask when you can ring again to find out whether all the enrolled children have actually turned up and whether there is a space. This kind of polite persistence often pays off.

Thing 2: I don't know why we load these expectations onto ourselves. Being at home alone with small children is an incredibly tough ask, and no-one likes to admit that they might not enjoy the task at hand. Having a strong willed child adds to the challenges. It's ok to feel the way you feel.

Thing 3: We all need to fill our own tanks. It sounds like you're running on empty. Some time to yourself, some variety to own routine, will help charge you back up again. This is a good thing and not something to feel guilty about.

Thing 4: Lots of kids get ratty when they are ready for kinder. Once you get past the transition and into the new routine, DS will have more outlets for his energy and his curiosity. You are likely to find that the time you spend together is less fraught with conflict.

Breathe - acknowledge your feelings as valid. This will pass
