Engorgement is inevitable. Every new mom will get it right after having a baby, when your milk comes in. For some, its not a big deal. For others, its huge. Like me, I probably doubled in size in 2 days. The pain is awful. So having something that really works to help sooth the pain is a must. I would recommend getting at least two sets of these. You will want a set in the fridge ready to go when you need it, and you will want another set to be warmed up right away in a bowl with warm water. It will help with the swelling, and it also encourages let down while pumping.
