DISCONTINUED The Flip nappy system allows you to choose which insert you use in your nappy. These are the Flip Cotton DAY inserts. They are made of soft cotton which opens out into a large sheet to give much greater surface area to speed drying further. This is a day insert for night time you'd need to use the Flip Cotton Night time insert.
Flips are a very economical system as you buy fewer wraps (the expensive part) than nappy inserts. The ratio of wraps to nappy inserts is 1 wrap to 4 inserts as a minimum. For a full time set this equates to 20 inserts (15day and 5 suitable for nights) and 5 wraps. If you have a very young baby you may prefer to get an extra wrap to allow for poo getting onto the wrap.
As the nappy inserts are just pads of fabric you are reliant on the flip wrap to keep poo inside so for a newborn especially a breastfed baby with explosive poo you'll likely to find you go through more wraps than you would with a shaped nappy but as long as you regularly wash your wraps so you don't run out this doesn't matter.
