It can be hard, my toddler DS is just going through assessment and is v likely to be more severely affected than my elder DS.
So we are now getting the usual looks and comments re our elder DS as well as comments about the younger..
'Oh why is he still in a buggy? There's nothing wrong with his legs!'
Then we invariably get asked why our middle child, a girl, is 'normal' - "why isn't she disabled then?' Ffs.
(We're waiting for wheelchair services to sort out a Maclaran Major, he's outgrown every buggy on the high street.)
DS has the mental age of an 18month old and a severe aversion to walking, but the height and weight of a much bigger child, which I'll happily explain if asked, and despite this, he's a lazy child, or naughty 
This forum saved my life, in so many ways.
It got me through both DLA and Statementing processes successfully, and in one piece emotionally.
It has also highlighted that there are still an awful lot of woefully ignorant, intolerant people out there, and how much we still need to fight to educate people, as well as somehow managing to do the best we can, for our children, to give them a better place to grow up in.
The women on here with disabled children aren't saints.
We're mothers who love their children and desperately want to give them everything they possibly can to make their lives as safe, comfortable and happy as possible, whilst dealing with exhausting full time care, frightening, worrying hospital appointments, poor schooling, inept medical staff, poor financial provision.
We do it day in, day out. For our children.
It can be heartbreaking and so frustrating to see the sheer ignorance, day after day after day, especially here, which for a lot of us is a safe haven.
