I'm wondering what could be the cause of milk bubbling when the mom
is pumping using a good grade electric pump.  It is the weirdest thing.
It almost looks like soap bubbles.  It happens on every pump we've
tried.  The mom is cleaning the pump properly - no soap residue or
anything like that.  What a mystery!
