Disana nappy in the day.
In truth, any cover that covers the nappy 100%, will work. Fit is really important with a PUL or fleece cover.

e.g with terry flats, which are a bit bulky, you might have to size up your cover. LIke you might have smalls to go over fitted nappies, but need a medium to go over the flats.

Night Nappying
Yes, it is a very different beast from day time nappying.

Day time nappies might be on for two hours
Night time nappies might be on for up to 12 hours

Day time nappies often are made up of HALF the number of absorbent layers that a night time nappy will have/needs to have. So night nappies are by nature, very bulky. Which is why night covers need to be all encompassing, like the Disanas.

What do we use as night nappy under the Disana?
because i have a baby who suits narrow crotch nappies and side snap closures, we have mainly those styles
- Lotus night nappy
- whizz kidz nightz
Wool knitted covers are so flexible, they will go over any night nappy.

I would show your partner the WHY WOOL link on the nappycino forum - to explain how it works.

For the first few months, i think a itti bitti boo fitted or a cute tooshies bamboo delights, would be a good night nappy.

i was amazed how soon my bub really did need a designated night nappy.

It's very useful to have a stash of boosters and inserts/trifolds on hand, to boost night nappies - it's a work in progress, working out exactly how much absorbency your child requires.
