I bought a sample pack from LL in a size 2 a few months ago and the wrap only just fitted over the nappy, how it should be I thought .....
But then my RNW free sample arrived and the size 2 wrap with that nappy was much bigger - so I phoned LL to question this and they told me they have changed factories and sizing of wraps may vary - but to send the smaller one back and they will replace it for me with a new one free of charge.
They are so freindly and really helpful - give them a ring I am sure they will help out if they can
My Anais is only 17 pounds at 20 mnths lol .......shes only just went into a foward facing carseat at 18 mnths....even though shes not the weight, but i figure shes old enough. Shes short too, so a very tiny girl, shes only 74cms tall
