Some cats aren't good at weaning the kittens. You may need to physically separate them for a few weeks to break the habit. I would have a vet check out this new lump. It may be normal, or could indicate infection, a cyst, or breast cancer. The vet will examine the lump and may take a sample of cells to look at under the microscope to see what could be causing it.
