I am not 100% sure hun, DD1 goes to 3yr old kinder now and there are 3 teachers (1 main & 2 support) and then there are 1-2 parent helpers a day with 20 kids in the class.
One of the boys had an OT come to his first day of kinder and they set out a plan of action for him, what he requires from the teachers, helpers etc and what the best course of action was for other parents and children.

All i can suggest would be that she speak with the local council and prospective kinders and ask what support they can offer her, if they would allow an aide to work with her or if they could allow 1 staff or parent member to be with her for most of the day IYKWIM.
