most of the time swirling strongly works, there are sometimes it does not which is hard. i can confess to couple of times where i really shook it upside down, sideways etc no avail.
I also move containers, as combining two chilled bottles into a bigger container so i can take the bottles to work OR putting the left overs of the day into a bag to freeze (never been warmed ones) etc. It will be interesting to observe if this happens as badly after taking lecithin for a while.
So, I did something last night while taking a hot shower. I took a handful of epsom salt, and massaged my breast w it...not sure if it helped a lot or not, but my breast felt good and soft enough to hand express in the shower for a while. I think now the remaining mass is newer milk trying to get through and not 100% old milk....miss optimistic here :-)
