Littlelamb bamboo nappies (also called "fitted nappies") are beautifully soft and extremely absorbent. They are also very reasonably priced. They must be worn with a waterproof wrap on top.
Each nappy comes with a double layer cotton booster to increase absorbency further. This is removable in the size 1 nappy so the nappy can be made slimmer for a small baby but the booster is attached in the size 2 and 3. The Littlelamb bamboo nappy is perfect as a night time nappy when used with an additional booster. They fasten with Velcro tabs making them easy to use and the tabs can cross over at the waist so the nappy can be made a tighter fit for a smaller baby.
Like all bamboo two-part nappies, Littlelamb bamboo nappies are very absorbent but it also very slow drying, so a lot of people keep them for night-time use and have a quicker drying but less absorbent pocket style nappy for daytime use. Remember to fold the laundry tabs over to secure them before the nappy goes into the bucket or washing machine. This prevents the Velcro picking up fluff in the washing machine and makes it longer lasting - and also stops the nappies all joining together in the wash.
Littlelamb fitted nappies come in three sizes but the vast majority of children will only need the first 2 sizes. Chubby babies will need a bigger size than tall slim babies of the same weight. A bigger size of nappy can be helpful to give extra absorbency and allow room for extra boosters for a heavy wetter or a baby who sleeps through the night.
Size 1 fits from 7 to 18lbs - a neat fit on a little baby and not bulky like a one-size nappy.
Size 2 from about 18 to 35lbs - big enough for plenty of bedtime boosters.
Size 3 for toddlers and children who still need nappies at night 35lb+
