Product Description


The mioboost is the perfect addition to any reusable nappy system by increasing the absorbency of any reusable nappy. Made from a highly absorbent, lightweight fibre, the mioboost is ideal for use as a nappy for newborns and smaller babies or to compliment the mionappy to maximise absorbency. Use alone inside a miosoft nappy cover (size 1) for newborn and small babies or with all types of reusable nappies to maximise absorbency – perfect for overnight use.

The Bambino Mio two-piece reusable nappy is now firmly established as the most popular choice of reusable nappy system, being the top selling brand in the UK and with awards being received from both parents and trade alike.

Pack contains 3 x mioboost.

Brand Information
Bambino Mio Nappies
There's a reason Bambino Mio Modern Cloth Nappies are the most popular brand in the UK...they are awesome! Super easy to use, these nappies are a great option if you are wondering if cloth nappies are for you. Sleep Store founder Louise used them a lot with her youngest, as it was the first brand of modern cloth nappies she found easy and convenient. They are great for day use and perfect overnight with the Night Boosters. If you can use disposable nappies then you will find Bambino Mio equally simple. They wash up really well too. We also love the cute and practical Bambino Mio swim nappies. The award-winning miosolo is a simple, stylish and super-soft all-in-one reusable nappy which is as easy to use as a disposable!
