Sorry - I've been away for a long weekend and just got back!
Yep i use them and find them great!
I have ordered 3 lots from little lamb in total, the first ones were long and thin (fit nicely in bumgenius and other pockets.)
The second lot - they accidentally sent me the small instead of the large - but they are good for extra boosting in night nappies, and the third set are the same length as the first and slightly wider but again fit very nicely in the pockets - it makes it easier for me to know which are the older and more absorbant ones - and which haven't had as many washes yet!
They are fantastic value - and i've been using them with the newborn insert from the BG's with no problem - and Charlotte is a heavy wetter! and they are nice and slim too!
