Some Napa County mothers are doing what comes naturally outside the local Social Security office where a woman was asked to take her breastfeeding outside last week.

About two dozen moms and their children staged a nurse-in on Monday to remind government workers that California law makes it legal to breast feed inside federal buildings.

Cherissa Lowgren said she saw a security officer tell another breast-feeding mom who was nursing her baby inside the Social Security office July 10 to leave.

Social Security Administration spokesman Deogracias Santos called the woman's experience an unfortunate event and says the guard probably was unaware that mothers have the right to breastfeed where they want.
