Yes this happened and happened to me. Although they sent him home sick when he was clearly fine. I took him to the GP then took him back to school and made a complaint. I removed him a week later and sent him to a special school.
And no, I didn't once look at my parenting as DS was beautifully behaved at school. School were not willing to make allowances for his disability, and by that I don't mean anything expensive, they wouldn't allow him to wear his ear defenders or have a chew buddy because 'he will look different'
Shock horror as soon as I moved him into a good school his behaviour was as perfect as it was at home.
But clearly according to stitch I'm just a bad parent. Clearly. That's why my child has a heart condition, no control of his body temperature, seizures, autism and severe learning disabilities and a phasical degenerative condition.
Clearly it's because I'm not doing enough with him at home.
Oh wait, that can't be right because the outreach service, complex needs team and home care says his home environment is set up amazingly just for him at the detriment of myself.
So maybe it's because I let him have that fruit shoot that time...
Some people are just horrible about children with SN.
