Question 1: What do liners do?
There is a difference between liners, inserts and boosters. Confused yet?
liners: Liners are either a piece of material like fleece or a flushable liner made from a similar material to baby wipes. Liners sit on the top layer of the nappy and it means that you can tip poo down the toilet without having to fish the nappy out of he bowl when you drop it. In a pocket nappy, you probably won't need to use anything too substantial. I use fleece liners but that is because our bamboo nappies don't have a fleece lining built in and fleece keeps baby's bottom nice and dry as it wicks the moisture away.
Inserts: Inserts are the material that you stuff the nappy with. They are usually made from, cotton, bamboo or hemp. A nappy is usually supplied with inserts.
Boosters: Boosters are what you stuff a nappy with when you realise that you have a wet leg and you only changed the nappy an hour ago. They do what they say on the tin and give a few layers of extra absorbancy.
2) Do you change the nappy each time?
With pockets and fitted nappies you'll need to change each time. If you were using fitteds with a wrap, you would be able to use the wrap if it was still clean. Snap in One nappies like the Itti Bitti Dlish can also be reused by taking out the inserts and snapping more inserts in.
3) What is the best way to wash them?
I wait until my bucket is full and then I shove them all in the machine with a quarter of the reccomended amount of washing powder. If you can smell the powder on the nappies you've used too much. It can affect the absorbancy of the nappy. I stick ours on a 60 degree wash but I'm thinking of dropping down to a 40 with 60 degrees if Ed is ill to make sure that bugs are zapped.
4) What is the best powder?
I think that this is completely personal choice. I use Persil Non Bio but only because a massive tub was on offer. We're moving to Eco Balls once the powders finished but I've heard that they don't keep the nappies very white so it really is each to their own.
We are loving our fitted nappies with wool. If you haven't been sucked into the world of wool BEWARE.
wool is great for night times because it lets some of the wee evaporate as the nappy can breathe. Not only that, you don't have to try and find trousers to fit over that gorgeous big bum because your nappy cover is the trousers.
I hope that helps. If you have any more questions then keep posting. I'm sure other people have different answers to me so you should get a good rounded opinion.
