I think he is just trying to make a general point that many children (not specific children with various health issues such as prematurity, of course they should have extra support and help). are turning up to school at the ages of 4/5 not potty trained at all. Parents surely must take some responsibility for this. 1 teacher, 30 plus children with what appears to be levels of up to half the classes not potty trained. This is an impossible situation for the teacher, disruptive for education and difficult to time manage and not good for the child. Along with issues of an increasing lack of discipline in some very young children, teachers are leaving in their droves, we are in crisis. They are teachers not parents and do a fine job caring for our little ones in exceptional difficult circumstances these days. I was a working midwife and mother of 3 children. It was expected among parents of reception classes to try to ensure children were potty trained Potty training surely is a parents responsibility not a teachers. I don't remember any child in any class not being potty trained or virtually there. A busy state school with 30 plus in the class.
