HI, sorry for delay in replying! Hard to find time to upload pics but done it now!
I have stripped them recently so don't think it's that.
Inserts:
I do just use whichever the napppies come with - CB large microfibre, LL bamboo x2, Totsbots as they are, not boosted. Have 2 Bambino Mio AIOs too. I think I should maybe just boost them more. I like the bamboo ones as they are thin so not too bulky. Haven't tried hemp! I will get onto the classifieds

We were just out for an hour, DS was probably in his nappy for 1.5 hrs tops, and it leaked (LL pocket with 2 bamboo inserts). He was either in the pushchair or on the swings for all that time, so I don't suppose the compression helped, but as a 6 month old there's not much he can do that doesn't compress his bum

Good to know this is the worst stage for leaks ha!
Fit:
So here is a leak, husband put it on tighter than I would have so maybe it's not the best example:
And I put a new nappy on, this is the fit I normally get - is it too gappy? Tends not to leave marks (when husband puts them on they do sometimes leave marks around legs).
Thanks soooo much for any advice
