Not too long ago, same mum was dropping child number 2 off. I was actually here this time as was waiting to take Skye in...she was telling the other mums how child 2 had been up all night coughing and spluttering and was full of cold but was not staying off. Mums were staring daggers at her xD
Luckily, child 2 is not in my daughters class, or even anywhere near her.
Skye still ended up ill a few days later, most likely after little brother caught the cold. But thats different...you cannot keep one off on the basis they MIGHT be contagious or might catch a bug. But if they are already ill then they should be off...
So yeah, it may be hearsay but she has previous for it so I am obviously going to assume the teacher is right again
Rather wish I was fit enough right now to take Skye back to school myself once she is better, could be useful speaking to neglectful mum.
