The Coast Guard says the baby, along with her parents and 3-year-old sister, boarded the USS Vandegrift at 8 a.m. Sunday. The baby girl was in stable condition and was heading to San Diego for medical treatment.
Authorities said the 36-foot sailboat, which lost steering and communication abilities, sent a satellite call for help on Thursday.
A California Air National Guard crew parachuted into the water and reached the boat Thursday night. The crew stabilized the girl and stayed by her side until the ship arrived.
A relative said the girl's family was attempting to circle the world.
