Shaped 2 Part Nappies

Absorbent material nappy which fits snugly around your baby.  Used with a separate wrap

so you are required to put on two layers. A shaped 2 part nappy is probably the most leak proof of

all nappies and works particularly well on young and new born babies. It is incredibly efficient at

containing the runny poo so often associated with younger babies. (Washable nappies leak less

than disposable nappies.  Shaped 2 part nappies leak less than all other nappies.)
Wraps
Covers/outer part used with a shaped nappy. You need to buy about
1/3 of the number of wraps to shaped nappies as you can usually use them 2 - 4 times before washing. 

PUL is the most popular wrap as it is waterproof and keeps wetness away from a babies clothes. 

You can also get wraps made from wool and fleece, these wraps are very breathable but not completely

waterproofed so leaks and wicking can sometimes occur.

All-In-One Nappies
Just one piece to put on, ie. the nappy and wrap are one piece, so this nappy is very easy to use and

similar to using a disposable nappy
Pocket Nappies
Also a one piece nappy to put on.   They consist of a booster/insert and a waterproof outer

layer.   It is a bit like an envelope which you stuff with an absorbent booster/insert. The  big
advantage of pocket nappies is that because the nappy separates it dries very quickly.
'One size' verses 'sized' nappies

The advantages of buying a 'sized' nappy  (ie small, medium or large) is that they fit your baby 

well and are slim fitting and neat.  If you are planning (if you can ever plan these things) to have more children,

particularly if you would like a small age gap between them, then it is likely you will have two children

in nappies at the same time.  'Sized' nappies then become the obvious option.  You are able to use

the small size on the new born baby and the larger size on the older child. They will last

you longer in terms of wear and tear as your baby will only be in each nappy for a period of 6 - 18

months.   The downside is that they will cost a you more money. 

The main and big advantage of buying  'onesize' nappies is that they are very economical.

You only need to buy one size because the nappy grows with your baby . If this is your last or only

child you are well advised to buy at least the majority of 'onesize' nappies

The disadvantages of 'onesize' are that they are usually very bulky on newborn and smaller babies.  

(Babies do generally grow very quickly in the first few months, so bulky nappies are only a problem for the

first 6 months or so and your child will be in nappies for at least 2 years if not longer).  There is a chance

the nappy will become too small before your child is completely out of nappies.  You may find it useful to 

have a mixture of 'sized' and 'onesize' nappies in your kit.  This will give you the economical benefit of

having some 'onesize' nappies but you will also have the advantages of  some 'sized' nappies that fit really

well while your baby is small.
