We have "gray standard, size 7" for chosen because the cloth was also attached to my husband and to the colorful simply not found so intoxicating. Is also conveniently portable to all (even for evening dress).
We use the cloth even now, although our daughter already crawling and standing. The various wrapping techniques are described in the enclosed book and well illustrated, so you can quickly bind techniques for "bigger" kids. Even if we need it at home is not much, it really has proven itself for example at carnivals, fairs, or the like. Our daughter can all see what she wants, but when she needs rest simply cuddle and possibly also easily fall asleep.
Frequently heard counterargument: You verhätschelst your child! How should it be self-employed?
My experience: Our daughter is very open-minded and enterprising. You want to discover everything and liked everything at once. That's just her personality and is independent of the sling.
We enjoyed it very comfortable for living and therefore I can only recommend it.
