Can you not stay with her at kindy for a few hours or a few days?
I can quite distinctly remember my mum staying with me and with my younger sister at akinder for a little while, plus we had parents on rostered help days...?
I am in WA now, but grew up in Melbourne - the whole school(pre) system over here baffles me so pardon my ignorance.
FFIW Charlotte started going to day care 2 days a week a few months ago. It took her a while to get in the swing but once I left she was fine, as soon as she saw me in the afernoons she would burst into tears lol But she is fine, loves it in fact, just a new environment and not having mum takes getting used to.

Keeping her home until year one though personally could be more detrimental that beneficial for her. Sometimes things aren't easy but we need to do them.

Good luck
