We have a very active little man who always movement needs (7mon.) And have been thinking whether we should get him a indoor swing or a hammock (Hopser comes because of our doorway not in question). This swing now, because it is long used (up to 30kg) has a belt and because the children can see more than in the hammock! But in the beginning you need ne blanket or a pillow to the child's head to protect them from the wood. Highly recommended!
