Please! Dont keep your child back just because some childcare worker thinks your child may not be developing at the same rate as the other children. I am an early childhood educator, and I see this all the time. I have only came to work in child care in rescent years, but before I did my studies I held my son back from his first year in prep because he was so much smaller than all the other children, and he was one of those children who was off with the fairies most of the time at his daycare, And his childcare provider informed me at the time that he would benifit more from have more to to develop socially before sending him to school. BIG MISTAKE!
I kept him in childcare another year and he was so bored and lonley without his old friends who went off to big school without him. Being in childcare didnt benefit him socially at all, it wasn't until he finally went to school he bloomed. He was the most happy and social kid I have ever seen. He is 10 now, and in grade 4 but everytime someone ask's him what grade he is in, He replies " I'm in grade four but I should be in Grade five, Mum held me back". It hurts me every time I hear it because deep down I know he was ready I was just holding him back to keep his carers happy..
Let your child grow at there own pace, and trust that they will be able handle themselves in all future social settings, with just your support, kind word and wisdom. Early childhood eductors dont always know whats best.
