I read that you would have to drink about 4L of HIV infected saliva to catch the virus.
Looking at the CDC guidlines should clear things up a bit.

Households
Although HIV has been transmitted between family members in a household setting, this type of transmission is very rare. These transmissions are believed to have resulted from contact between skin or mucous membranes and infected blood. To prevent even such rare occurrences, precautions, as described in previously published guidelines, should be taken in all settings "including the home" to prevent exposures to the blood of persons who are HIV infected, at risk for HIV infection, or whose infection and risk status are unknown. For example,
Gloves should be worn during contact with blood or other body fluids that could possibly contain visible blood, such as urine, feces, or vomit.
Cuts, sores, or breaks on both the care giver’s and patient’s exposed skin should be covered with bandages.
Hands and other parts of the body should be washed immediately after contact with blood or other body fluids, and surfaces soiled with blood should be disinfected appropriately.
Practices that increase the likelihood of blood contact, such as sharing of razors and toothbrushes, should be avoided.
Needles and other sharp instruments should be used only when medically necessary and handled according to recommendations for health-care settings. (Do not put caps back on needles by hand or remove needles from syringes. Dispose of needles in puncture-proof containers out of the reach of children and visitors.)

Saliva, Tears, and Sweat
HIV has been found in saliva and tears in very low quantities from some AIDS patients. It is important to understand that finding a small amount of HIV in a body fluid does not necessarily mean that HIV can be transmitted by that body fluid. HIV has not been recovered from the sweat of HIV-infected persons. Contact with saliva, tears, or sweat has never been shown to result in transmission of HIV.
FEOS, I am sure you are a good dad, so your are keeping your kids safety a priority. I just wanted to point out that there would be almost zero chance of transmission unless the HIV infected nurse was bleeding all o ver the place.
