Many forms of gentle herbal treatments are available for infants where they can either be breathed in or absorbed through the skin. Anti-colic tea in the babys bath tub is a wonderful way to provide relief.
It is made from a handful of catnip and lemon balm added to a quart of water and steeped until lukewarm (at least 15 to 20 minutes). If the mixture is still hot, add cold water before straining into the tub.
