At my 4 year old DS's new school the children all take packed lunches. Before he started I was given a note saying no sweets were allowed in school - fine, I support this. On the first day I sent him in with a snack of mixed nuts (unsalted). A note came home saying no nuts were allowed because they could be a choking hazard. So on the second day I sent him with no nuts, and a chocolate flavoured yoghurt for his dessert which looked frankly disgusting but I'd bought it by mistake and nobody else was going to eat it. A note came home saying chocolate is not allowed in school so it would be 'preferable' if he did not have chocolate yoghurt again. Yesterday I sent him with no nuts, no chocolate yoghurt, but a handful of plain mini-crackers as a snack. A not came home saying no biscuit snacks. I can't keep up. Thinking of putting a note in his bag asking to be provided with a complete list of foods which aren't allowed in school, or for a new parent might that be construed as a bit passive-aggressive and rude?
