My book was a hardback flower spotting guide and I loved it; the two flowers that I remember being REALLY chuffed about spotting were Cowslips and Pink Campion, I can still identify Pink Campion from a hundred paces to this very day!
I love books/activities that get children involved and up-close-and-personal with the outside world around them - far too many kids are walking around with their eyes closed and miss all of the amazing things there are to see and appreciate.
The Usborne's Big Spotter's Sticker Book has over 300 stickers of all sorts of things for your child to spot, things like: common flowers, tree, birds, insects and animals - every time your child spots something in the book, they can stick in its corresponding sticker.
The usual price for this Usborne's Big Spotter's Sticker Book is £9.99, you can grab a copy for £3.49 by adding the JULY2012 promotion code to your basket before you check out.
Single item delivery will cost you £1.95 (you need to spend over £25 for free delivery to kick in and there aren't any active free delivery codes floating around at the moment, I've looked) but even so, all in it's still a great price for a great book.
Happy spotting and sticking!
