Like The Jolly Postman Books? The Peppa Pig: Peppa's Post Book is along the same lines as in it contains letters with contents for children to pull out and explore. I have been looking for this for my Peppa Pig daft son and I know he will adore it. Amazon are selling it for just £6.49, which is good considering it's normally £9-£12 in the shops.
The Peppa Pig: Peppa's Post Book contains six envelopes containing various things like theatre programme and an invitation. Books like this encourage children to explore and really pique their interest in reading.
This is suitable for younger kids than that of The Jolly Postman and is a nice addition to any little ones bookshelf.
You can have the Peppa Pig: Peppa's Post Book delivered for FREE when you spend £10 or more on books at Amazon or if you have Amazon Prime. Otherwise postage will cost you £3.30, so you are better off spending the £10.
