I (8 months) for our son brought this swing and the door frame fixed (separate Schaukelhaken and pull-up bar for purchases). He sits very stable in it and how it should be right on the ropes clung while rocking. Here we get well "quiet" asked him when we have lunch or dinner, but he had already received his meal. Always take occasional nudge and he grins up a while rocking (like well what Doller - the small roller coaster junkie ;-)). The belt can be additionally around the gut stabilize him something so that he can not rush out themselves. I think in the summer I'm going to the swing sometimes outside ans then existing climbing frame hanging for "Outside" -Schaukeln. Because it is plastic, the rain is the things do not already.
