RayRay - I can't believe they are doing that at the centre. Is the centre part of a large chain? - if so i would go straight to the top with this one. I don't see how they can be fostering each individual childs development running the program this way. When i worked in childcare - i had to keep developmental records on each individual child in my class, and tailor the program to suit their individual needs. There is no way the programs are going to be able to run in this way if staff are changing weekly.
I hope lots of other parents join you in complaining so they don't even get to trial it.
