I always keep a look out for story tapes and never really find enough to keep the mummy bordom at bay. Pretty princess at ELC is a firm favorite with my two and winnie the Pooh read by Bernard Cribbins from Amazon I like. My mum found a lovely paddington bear at her locaal book shop. I admit that some of the lovest tapes I have found have been in cheap bookshops, they have obviously been remaindered and they have really good narrators, like Jon Pertwee. I'd love to find somewhere that do more tapes that he read.
Sorry a bit long winded way of saying I have thje same problem!
