Síne is 4 months old now and she drools a lot, so I get this Combi teether (it's for 6 months old, but I figure she likes it better) for her and I am right. She loves this teether and she can chew it for over 30 mins. The bright colour catch her eyes and she likes the sound when she shakes it. DC said Síne uses her tongue to lick on the shape to build up the 3D image, I guess I have to clean this toy more often then. It is so amazing how it calm her down and keep her busy for 30 mins. It's been 3 days and she is still excited to see it. This toy is worth it then.
