Great for the early days
I used these during the early days of breastfeeding. My son had to have medication 4 times a day when he was born which was mixed with breastmilk. This was perfect for collecting the amount needed for each medication time without having to drag out my electric pump each time. It helped to ease the soreness of my nipples in the early days by having these in for a little while in between feeds. They stopped me leaking through so many breast pads and by collecting each little bit of milk and storing correctly, I was able to have enough to make up a whole bottle at times. I hated the thought of wasting precious breastmilk and this was perfect for that. The only downside was they weren't that comfortable to wear for a long time or to wear to bed etc.
