All-In-Ones (AIOs) are by far the simplest type of nappy to use in terms of speed and convenience. They are the most similar to a disposable, where the whole nappy is sewn together to create a single item. They are not the most absorbent nor do they perform the best on containing the inevitable poo explosions, however new types come onto the market fairly regularly and they are improving. It is often possible to ‘boost’ an all-in-one nappy with extra inserts to make them more absorbant. Examples of an all-in-one nappy are the Bambino Miosolo, and the Bambooty Easy Onesize.
