Today is Foster's 4'th birthday! Visit the Aquarium to wish Foster a happy birthday & to see our entire dolphin family! http://aqua.org/tickets Foster was born at the National Aquarium on September 9, 2007. He got his name because of his unique upbringing. Since Jade was a first-time mother, experienced moms Shiloh and Chesapeake helped her raise Foster. All three females nursed Foster when he was a baby. This is a photo of Foster on his 1'st birthday!
