Life is what you make of it, just because other's have, what looks to the outside world, as a 'perfect' life, doesn't necessarily mean it is....they just don't feel the need to ram it down other peoples throats.
I'm sure Laura must feel less than 'perfect' in her mother's eyes, otherwise why would Den keep going on about it. I feel Laura is quite capable of going through life without the stigma of Den's constant " meet my daughter, she's special needs" afterall she has a job and quite a few friends, so she can obviously stand on her own two feet.....I think Den uses Laura for sympathy and 'look at me I'm burdened by my child'.... I, personally, think it's disgusting, especially on a much watched satellite channel.
