These beautiful reusable breast pads are perfect for nursing, and I can vouch for them as I have tested them myself! 
 
They are made of three layers:
 
1. Cotton - pretty fabric for the outside
2. Terry Towelling - absorbent and soft against the skin
3. Flannel - 2 layers of flannel between the other two layers for absorbency
 
Despite the multiple layers, the breast pads are still slim and fit well in tight clothing.
 
TO WASH: rinse well after use, hand or machine wash. It is recommended that you place the face wipes in a small bag when washing in a machine so they don't get lost. We do sell wash bags in the shop drop collection!
 
These can be tumble dried, but line drying or on the window sill in the sun will work as well.
