Dd (8) went on a school trip yesterday in a heat wave, 40 minutes each way walking to and from a museum.
I sent dd with 2 bottles of water and she didn’t drink either of them and a hat which she didn’t wear.
She arrived home with a headache and has had diarrhoea since.
I know this was partly down to her but she is juts a child and nobody encouraged her to wear her hat or drink anything all day.
I applied sun cream before she went so at least she had that.
