Tuesday November 11, 2008 (foodconsumer.org) -- Britney Spears' 2-year-old son suffered a reaction to something he ingested this weekend and lawyers were talking about the potential implications of the incident, media reported.

Britneyspears.com released a note on Nov 10 saying "Jayden James Federline was admitted to the Southwest Mississippi Regional Medical Center on Sunday, November 9th. Doctors concluded he had a reaction to something he ingested."

The boy has been released from the hospital, probably on Monday evening, according to a report on Monday on celebrity website tmz.com while the statement on Britney Spears's official website said Jayden was expected to be released Tuesday.

Not much detail was known about the reaction. But People magazine quoted a source close to the Britney Spears’s family as saying that Jayden suffered an allergic reaction and he had itchy and irritable hives.

The incident happened during Britney Spears' trip to Louisiana, her childhood home. The Pop Star had been allowed to leave California with her sons for the first time since the custody of her boys was given to their father Kevin Federline in July, Reuters reported.

It is very unlucky for Britney Spear to have had the incident.   If she knew that her son are allergic to certain food and let him have it, it could be a case of child neglect, which could lead to a modification of her already restricted custody of her sons, L.A.-based family law attorney Lynn Soodik was cited as telling eonline.com.

Food allergy is a potentially life-threatening reaction by an individual's immune system to a food or food ingredient and as many as 6 to 8 percent of young children suffer from food allergies.

The most common allergens for young children are cow's milk, eggs, wheat, soy, peanuts and tree nuts. If a child has allergy to a food, the best way to treat food allergy is to avoid the food.

But it is not completely understood how people get allergy.   In the U.S., and some other countries, pregnant women and nursing mothers and babies are advised to avoid the common foods that cause allergy.   

However, one recent study suggests that exactly the early avoidance of exposure to the common allergens may actually increase the risk.

Food allergy is very uncommon in the poor countries.   It is unknown whether lack of breastfeeding and extensive use of vaccines have anything to do with allergy in the developed countries.

Whether Britney Spears were negligent depends on whether or not she knew her son is allergic, according to Soodik cited by eonline.com.
