The CDC has released new guidelines for moms concerned abouth whether they should breast feed their children if they have H1N1 or Swine Flu.
"Infants are thought to be at higher risk for severe illness from novel influenza A (H1N1) infection and very little is known about prevention of novel H1N1 flu infection in infants. If you are breastfeeding or giving your baby infant formula, a cautious approach would be to protect your baby from exposure to the flu virus in the following ways:
Ask for help from someone who is not sick to feed and care for your baby, if possible.
If there is no one else who can take care of your baby while you are sick, try to wear a face mask at all times when you are feeding or caring for your baby. You should also be very careful about washing your hands and taking everyday precautions to prevent your baby from getting flu (http://www.cdc.gov/flu/protect/habits.htm). Using a cloth blanket between you and your baby during feedings might also help.
If you are breastfeeding, someone who is not sick can give your baby your expressed milk. Ideally babies less than about 6 months of age should get their feedings from breast milk. It is OK to take medicines to treat the flu while you are breastfeeding."
