Do you attend any playgroup now? My bb is also a small gal so when she has no pn experience when she starts her K1 interview last year. I talked to her playgroup teacher and they allowed us to leave her to attend the playgroup herself while we are sitting at the very back of the corner. A week after that we go outside the room but keep monitoring her at the door (the room is a glass room so can see the inside situation clearly. my bb attends this playgroup from 1 so she's very familiar w the area so no prob w her. you can talk to her playgroup teacher and see if she can have a try.
The best thing to do is take your daughter to the interview school to have a look at the outside before the actually interview. Tell her what will she do at the school interview. I tools
Y daughter to playgroup twice a week and the school is on the way to playgroup so I always stop outside the school and show her, tell her we will go inside the school soon to meet new teachers and friends. Then almost everyday I wil ask get what should she do when we meet new teachers, we should say hello be polite and answer all teachers' questions. Trust me it really works!
