Petit Lulu Snap in One (SIO) Complete is an "all in" nappy system. Buying the "Complete" sets on this page saves you money compared to buying the components individually.
Petit Lulu SIO Complete = Petit Lulu Classic Cover + Petit Lulu Classic Insert Set.
The outer cover is made of PUL which means it is waterproof but also breathable. Unlike other wraps we stock Petit Lulu covers come with a fleece hem/binding. The fleece binding is really soft against the skin so no marks on baby and is a great insulator so limiting leaks. These wraps are popular with families with very sensitive skin who want the softest of nappy bindings.
The outer fastens with poppers. The poppers are underlaid by suedecloth and second PUL layer which makes the product long lasting and gives you better performance.
Fits 5-16kgs (10-35lbs).
The nappy gives you 3 length settings: Small, Medium and Large. The length is altered using the poppers on the front of the nappy.
The waist is altered using the double row of poppers along the top. This is my favourite popper fastening positioning as it holds the nappy firmly in place and minimises wing droop.
How do I use it?
The Petit Lulu SIO is highly adjustable with poppers at the waist and poppers to adjust the length. This gives you small, medium and full length settings so that the nappy gets longer as baby gets taller.
Each set comprises of a waterproof outer cover and a popper in absorbent bamboo basic start insert. The insert poppers into the outer waterproof cover to keep it secure and prevents it moving around. At change time you simply unpopper the soiled insert and pop a fresh one inside. We recommend changing the outer waterproof wrap after two nappy changes to ensure the outer wrap is kept clean and fresh. This means you will need half the waterproof outers to how many inserts you have eg 10 covers and 20 inserts. This all in two snap in system makes for a more economical nappy system compared to all in ones.
