I am going to wade on in here...(hope I don't regret it).
I am a mum of a NT child (although I don't actually know what it is - I presume it means not SN, but don't know what NT stands for!)
In one sense I CAN'T understand what your lives are like, in a similar way that someone without children cannot truly understand what it is like to have a child.
But what I love about the SN board, is that I get a tiny insight into what your lives are like, by what you post.
Some people are rude and insensitive, or just ignorant. But some of us, who still will never understand (I do understand that), would love to understand.
I don't feel sorry for you because you have children with special needs. I feel sorry for you because knowing how exhausted I feel at times with my 17 month old NT child, I can't imagine the exhaustion you feel.
That's not pitying you, but imagining the emotional strain of caring 24/7 without a break.
Perhaps you could educate people like me? Not saying that you have to like us, or accept us, but please don't dismiss me or people like me as irritants to be avoided.
Hope today has been a good day.
