DS2 5 suffers from temper tantrums with low blood sugar. He generally melts down mid morning and mid afternoon. He has always done this - some tantrums I can see are due to low blood sugar as he is floppy, unable to control himself or do anything. Some are due to his own issues.
School work with us on this and have snacks in the cupboard for when they recognise he is about to turn.
However - should I look into this a bit deeper. It's not getting much better and I'm wondering if I should request a blood test.
