So I have had a big problem with recurrent ducts

They have been so difficult to deal with I can't even describe...
One thing that I noticed the other day that was really interesting that I wonder if others experienced too is that when looking at a bottle of my pumped milk I noticed that the milk is SUPER fatty. There is this thick rim of almost fat around the top of the bottle. If I pour the milk out I have to heat it up to get this thick milk to even move. Do others have this or is my milk just super fatty (and hence the plugged ducts)? I'm so curious if this is a uniform problem or an explanation for why I have been getting into so much trouble.
Re: Fatty breast milk - anyone else observe this?
