I have Medela, Bailey and Nursing Mother Supplies cotton nursing pads, NIP for sale. I had these in my shop I sold and the new owner did not take the inventory. Here is a run down of them:
Medela - thick, very absorbant, soft, and durable
Bailey - Not quite as thick, not sure about absorbancy
Nursing Mother Supplies - even less thick but "hide" well under shirt. Because they aren't as thick, they aren't as absorabant. (Personally, I have found nothing that absorbs like Medela)
All are $6.50 a pack PPD, 2 pairs per pack.
Medela's disposable pads are the best on the market. I did a test with these and others on the market with moms that leaked a lot. These won hands down. 60 ct box for $7.50 ppd and 30 ct box for $4.50 ppd.
