Again, I am behind in reading posts (it's amazing how many can acumulate in 36 hours!) so sorry if this is a repetition of what others have said. Here is my current thinking - subject to change if new evidence comes to light. I no longer suggest warm for initial engorgement/fullness in light of recent studies. I suspect that in these cases, the swelling that accompanies the establishment of full milk supply is the primary problem. Warmth only increases circulation/swelling. However, if a mom reports she is leaking freely and wants to let warm water run over her breasts in the shower, it is probably OK. On the other hand, with later mastitis and fullness, I think the milk volume/backup is more likely to be the problem and in this case, warmth can help.
