My daughter started at a new school today.The school made a big deal about making sure I filled in the forms about who collected her and handed it today or she couldnt start only for me to turn up to pick her up and find they don't have her. She had wondered out.We found her in the playground in a sea of parents,kids looking around and scared not far from the exit. The teacher blamed her and said she kept trying to find me but surely this would of made them keep and eye on her more.There is a teacher and 3 TAs.They have a system where they queue up out side in from of gate and she had gone through the gate while her teacher wasn't looking.In her previous school they didn't let children out unless the parent was there so she assumed I was outsid and behind the gate.Her teacher told her off and told me to make sure to tell her she needs to wait and that was that. Im in shock at what could of happened if she wandered out ,got run over or abducted.Imagine I had been late and they hadn't realised.My mum saying not to complain since it's her first day because and the teacher might resent me or my daughter for getting her in trouble with head but that sounds really backward.What should I do?
