as for compression leaks...
have only had afew..as Jack is ALWAYS wriggling..even in bed...hehehe
he sleeps in a night nappy with a fleece cover, he can out wee his NN but it NEVER soaks through the fleece/minky covers.
i did have BBH PUL covers but as i said he sweats heaps..so ended up with a rash BIG time....i have since gotten rid of the PUL covers.
