The all-in-one reusable nappy has the advantage of being the one that resembles most like the disposable version in terms of design and tends to appeal the most to dads. The AIO is the complete reusable nappy which contains the insert (the absorbent part) and which is sewn directly into the cloth nappy. The AIO gets its name from being only one piece and is therefore integral. It is therefore the perfect model for the day, because it is very practical to take with you. At Takaterra, we have taken care to select the models that are the most comfortable for baby and that do not leak! The best AIO reusable nappy, in our opinion, has a leak-proof outer shell. The All-In-1 must contain small effective elastics on the edges to hold the thigh and stomach. In addition, it must be scalable, especially if it is used directly for a newborn. With the multiple snaps, allowing you to adjust the size of the nappy, you can use it from birth (depending on the size of your baby) until the cleanliness acquired. The set can be washed directly in the washing machine. There's nothing that needs be added or removed. Just clips it and scratch it on your baby. If this is your first time going for a reusable nappy, then this is the right one to start with and the which is most used!
