YES INFECTION: Any infection, drugs that the mother has can be passed through breast feeding.That's why mom should not feed baby when sick to avoid infecting baby.

Yes & No: 1. Verify that the mother has mononucleosis or a mono-like illness; there are several viruses that cause mono or mono-like illness; 2. Ebstein barr virus is present in breast milk; studies show very little transmission mother to infant in that manner; there is some evidence mother to fetus transmission during pregnancy; CMV however is very transmissible; 3. Largest risk factor is saliva transmiss.

Yes: Mononucleosis, a viral infection, can be passed through breastmilk, but is not a reason to stop breastfeeding. The reason is that by the time that you think or know that you have the infection, you have probably passed it on to your baby. But breastfeeding provides many benefits, including infection-fighting, to your baby, and mono is seldom dangerous to infants and children. See a dr.
