If so I'd be grateful if you could tell me a bit more about it.
It's not for a baby - it's for my severely autistic teenage son. He's intelligent (yes officially he has severe learning disabilities, but he's intelligent). Quite capable of learning to read, but has huge language difficulties (this is partly why I'd like him to learn to read - I think it would help). He can read and write a bit, but knowing how to teach him is hard. He's recently come on so much - that I'd like to challenge him a bit as I think he gets bored at home & when we're not out and about.
Anyway most reading programmes require children to sound out words - this is the biggest stumbling block as he can't sound out. He can now write letters so there might be an option to get him to do that rather than sound out, but I can't imagine him agreeing to too much of that 
I was wondering whether because this book is aimed at babies whether it uses other methods, rather than sounding out. I don't want to buy it and then find it's unusable. If anyone could tell me a bit more about the methods he uses that would be great - thank you.
One book I found suggested online was teach your child to read in 100 easy lessons, although I know that is aimed at typical kids so expects sounding out.
I wasn't sure where to post this - went for parenting as I thought some owners of babies with the book might see it rather than in education :)
