New improved Littlelamb wraps are said to be bomb-proof and flood-proof and very reasonably priced too! They can be used with Littlelamb nappies or any other shaped two-part system nappy, or with pre-folds. The gussets round the legs make for a very neat fit.
I only have size 3 left - for toddlers from 35lb (16kg+)
There are no laundry tabs so do up the tabs and turn the wrap inside out for washing.
