She is you're child, and if you and her teacher think she is more then ready to start school, then i wouldnt hold her back. Half the time teachers dont know what they r on about. Each kid is different.

As a teacher I take offence at this comment. We actually go to uni and study to be teachers, we don't suddenly get up one morning and think "hey I might be a teacher today"
Its rude and thoughtless comments like these which have devalued the teaching profession in the public's eyes.
