I bought this for my 7 month old as I wanted a soft ball with a jingle. She also likes materials and crinkle noises so thought this would be great. However she has quickly become bored with it. It doesn't role because of the material flaps and so now can't be used as a conventional ball. I would however recommend this for younger babies - probably from 3-6 months.
My 7 month old loves these cubes. They are the right size to hold in a hand (so they are quite small - about 2.5cm / 1 inch cubed). The 3 touch/feel cubes are a little disappointing as the hole which holds the material is quite small and shallow and the material isn't that defined (so there isn't much to feel), but the other 6 are great. They are well made with smooth wood - very tactile. The bag they come in also gives much amusement.
My 7 month old loves these cups. I was looking for wooden cups, but these are much more versatile. They can be used in the bath or on the beach and are great for bashing together and hiding things, as well as the traditional stacking. A great toy.
I borrowed this book from the library before deciding to buy - the receipes have been excellent and it's great that there are basic recipes which he then shows you how to use in different ways. A good value book. Some receipes are already available on his website though.
