Thanks for you replies, I use wool covers, some longies and some interlock/couche, but nothing is working, have re-lanolised everything again just in case.
Have not tried lls nappies only covers so might have a look at them. Although his nappies are always wet, they have always been that way, can't seem to work out is there leaking from the leg or through the nappy??
Forgot about boosting between cover and nappy (did that when ds was little)
Will give that ago, also will have a look at the lls, so glad my fluff buying days are not completely over
