Yesterday, we got a call to pick DD1 up from school because they thought she had D&V. Apparently a few kids in her (small) class had D&V symptoms so when DD1 had a dodgy nappy and seemed a bit under the weather, they sent her home.
School know very well that DD1 is prone to dodgy nappies. She's hemiplegic so her digestive system is erratic, and sometimes she drinks virtually nothing and other times (eg when she has a cold) she drinks lots and as a result she can have a Surprise Nappy without their being anything much wrong. We have had conversations with them before about this.
So, I was OK with them sending her home because it might be D&V and might not so we watched her carefully. She wasn't herself for a few hours - often the way when she has a cold or something - then perked right up. No dodgy nappies. No vomiting.
This morning I kept her off just in case. She's fine. She's stumping round the house getting in the way of the cleaners and SCREAMING constantly because she is bored rigid and wants to be at school. She's had a truly miserable Christmas stuck in the house what with the dreadful weather and everything. We phoned school and said we wanted to send her in tomorrow because she clearly had not had D&V, just a cold.
School - after 20 minutes arguing on the phone - point blank refused to allow her back in. They said because other kids had symptoms too, they were sticking to their D&V rules and she could not come in for 48 hours.
Am I being unreasonable to be mad as all hell about this? Fundamentally, they are refusing her access to education because of her disability. If they keep her off every time she has a dodgy nappy she'll never be in school. I'm so mad I'm thinking of threatening them with the DDA/Equality act. 

Is that feasible?
