I am have just started watching this series. I am in my mid-30s and my younger brother (also now in mid-30s) is globally retarted- probably would now be called severe learning difficulties.
I don't have children but from watching this series I can now appreciated how hard it must have been for them as no-one really give him answers. I am not sure my parents would be able to watch this as it's all their fears and struggles on the screen, so qudos to anyone who is watching this.
As you can imagine the bit that effected me the most was the experience of the brother. I have an older brother as well, but being the sibling of someone with learning difficulties we very isolating as the only time I spoke about it with my parents was when they were writing their will and my mum had this book called 'what happens to your mentally handicapped child after you die'. She came into my room and begged me to make sure that my brother always had Pajamas (god knows what was in that book).
I can assure you that I love my brother very much and I wouldn't swap him for the world, It is ok to talk to your other children if you are struggling and scared. I definitely didn't suffer but I did find it very hard to always have to explain to people because I didn't really have the words.
I think this show is fantastic and it would have helped me talk to my parents and my school friends and family about what it was really like at home.
