i wanted one of these necklaces a few months ago 4 my ds but couldn't afford one so i went to a bead shop and made my own with cord and big colourful wooden and glass beads for under a fiver! Complete bargain! And theres lots of different colours and textures for ds to play with. my niece who is also 6months old and not breastfed (unfortunatly didn't happen 4 sil ) and she loves 2 play with the necklace 2 so i would def advise any mother with a young child 2 get one its good from an early age even 2 help with keeping their attention and encouraging them to grasp and hold an object
