A good way to start weaning

One way that I've found to be very effective fir my self and most of my friends is using Agave or Aloe Vera. Smearing a small amount on the breast before feeding is a great deterrent. Also you don't have to worry about it hurting your little one since it won't burn them like using vinegar will. It will just leave them with a yucky taste in their mouth for a bit.
