Bryan - does she have any interests? Animals, travel? Even magazines - cookery, sport, clothes etc can work.I was always enjoyed books but never the type Mum might like,and so am struggling to choose. Can I pick your brains, do you have any recommendations for books to try, I have ordered a couple of 'grown up' poetry collections but have no idea where to start in the kids section to find something Mum might like.
I would say, have a look in the children's reference section of a library, Dorling Kindersley publish lots of reference type books - animals, science, maps etc Lots of pictures and some text. Start with an interest she has.
If you are unsure, try borrowing children's books from the library. I choose classic titles, because we remember these - so Dr Seuss - Cat in the Hat or Green Eggs and Ham if she likes humour and ryhme. If you had books you enjoyed as a child, this may be a way in as she may remember reading them with you.
We also had success with the nonsense verse of Edward Lear - again a bit old fashioned but the nonsense element works well as she just likes the sounds of the words, they don't have to mean anything.
