For the first gripping attempts this Greifling is really very appropriate. The processing, the smooth wood, the rubber, which makes the side with the colored balls flexible - everything is very well done. The toy is light in weight. For The Child's wooden tactile pleasure and pedagogically more valuable than plastic. I can only washed (mild detergent) to dry, these Greifling and my 9-week-old baby enough. We are both very happy with it. It can also be great hanging on a 'Baby-gym' or take in the stroller when it comes to anxiety while walking times.
An update: I'd rather not give in boiling water for sterilizing. Did it today and seen that the color is the same melted. Now the rattle is unfortunately in the trash. :(
