Ok @myDHhasahobbyanditsnotcycling let's talk about what I do in those 15 hours shall we?
3 are taken up by a volunteering role for the local food bank, which I can do from home.
At least 3 are spent in the car picking up/dropping off DS.
Nine left?
3-4 hours cleaning the kitchen and bathroom throughly - because I can't do it when DS is at home.
At least 3 hours tidying/sorting clothes/hoovering - again, things I cannot do with DS is around.
Ok well I admit I may spend two of those hours drinking cups of tea and staring at the wall.
I have around another hour to sit wasting my time on Mumsnet. Ok I hold up my hands to that! Hello!
My son receives the highest rate DLA, which means he needs 24/7 care. He's awake in the night. He needs constant supervision. He cannot use the toilet. Or speak in sentences. Or dress himself. They don't just dole that out high rate DLA without a LOT of supporting evidence.
You ARE ignorant. And rude. And you've been called out on it.
