I have 2 of these in 2 different sizes.  The sizes were on point.  I definitely had to lanolize 3 times before it "worked."  I also rubbed the groin area together to felt it so that now it is barely porous in the high soil areas.  (Now it's bullet proof!)  I wish it didn't go so high up babys body though. (reson for my minus one star.) What's the reason for it going up so high?  It goes all the way up to the armpits!  Makes my kids hot while they are sleeping because of this, because it basically means they are sleeping in wool pajamas because it covers the entire torso.  I've started rolling down most of the top band.  I use these at night and I have been using it every night for about 3 weeks now and even though they are damp in the morning, after laying out to dry immediately after baby wakes up, there is no smell to them whatsoever.
