An older child could reject feeding from one breast if the milk supply is poor. Sometimes, there could be other reasons too for the mother to breastfeed the child from one breast. For example, infection in one nipple, mastitis or blocked duct at one side, one breast producing less or no milk or any other physical issues that the mother may be going through. Some mothers find it more convenient to hold the baby feeding at one preferred side, making the baby used to that one breast.
