thanks again all for the advises few weeks ago. Got my udnn Soy and using it. (and got some more too:)
I put the 2 soy inserts (the big folded and the smaller insert) + mf insert, 4 layers of hemp and 8 layers of bamboo and between wool and nappy 1 big bamboo insert folded and wool booster. And the coolmax underwear first of course.
Nappy is soaking in the morning, but no red bum, thanks the underwear and no leaks, thanks to the wool!!
ds is like a football of course and can barely walk but at least we are having dry bed and no rash!!:)
