The organizer has several compartments, which you can zoom in or out as needed. You can strap him, so nothing more is flying through the area, except for our son throws with books :). The bottle holder can not yet use (2). He is still too small and too tight the elastic band for him. So he does not get into it asked the bottle. We simply take the urge small compartment. As the bottle is also good in it, does not tilt to and he is easier to get. If he is older, he will thus get along.
One point deduction there from me only because the exterior walls could be a little more stable. But I'd go back for that.
