Our son got for Christmas the Rainforest experience blanket because he was just three months. Since then he is at least once a day and it would be always totally. Although he can not yet grasp properly, he already tried it diligently and juchzt all the time. The ceiling itself is too thin for cold floors, but if you what it is underneath lays a problem. We have a lot of fun with it and the battery also lasts a long time. (Caution: ungewöhliche Battery C LR14 places is not supplied)
