What size flats do I get?
Small flats are best for smaller sized babies that are born 3kg or under. Smalls can fit to 7/8kg using this hack. Usually can be worn for 3 - 4 months but if baby is born smaller than 3kg, can fit for as long as 5 - 6 months. If using smalls, you can upsize straight to large from 7/8kg.
Medium flats can be used from around 3.5/4kg by doing this clever hack. These are good to buy if you are having a bigger baby say 4kg+, or if you plan to only start using your nappies a few weeks after birth (around 4/5kg). They can be made to fit for as long as 8 - 10 months using this hack. You will just need to upsize the nappy cover at 6kg to the OSFM cover to continue to use them.
Large flats can be used from 7kg using the same hack as above. We do not suggest trying to use this size under this weight. It just doesn`t work. Large flats will fit to past 20kg.
Day time nappies
One flat and one booster is a standard day time solution. Flats have to be used with boosters. Two boosters may also be needed during higher output stages. Things change so be prepared to add this if needed. A fleece liner can be added closest to the skin in the first days to catch the meconium. They can also be used if baby is sensitive to wetness as it keeps the bum dry. We suggest having a pack of 10 at the newborn stage. When baby starts solids, one liner per nappy is essential.
Tip for newborns: Leave the booster out for the first two to three weeks when baby is tiny. Add it in the nappy or cover when nappies start to get wet, usually around three weeks old.
Night nappies
Newborns
Babies are changed through the night until around ten to twelve weeks old. One flat and 1 - 2 boosters is usually fine for a 3 - 4 hour stretch but not enough for more. If baby sleeps longer than 4 hours, fold 2 flats together at the same time watch our video.
6kg+
No changing is needed once baby stops pooping at night. This usually happens around 10 / 12 weeks old. Fold two medium or two large flats together and the OSFM waterproof cover. See our night nappy page here.
Best fold
Our firm favorite is the Origami fold for both boys and girls until it stops fitting (it starts to feel too short in the front). Then use the origami hack which gives the flat a good few extra kilograms of wear. This hack makes the flat longer to accommodates a baby getting taller.
