Heidi Klum and her boyfriend, Martin Kristen, took Heidi's son Henry Samuel to the beach in Oahu yesterday. The trio were back in the sand after a scary Easter Sunday, when Henry and two nannies were almost swept away by the ocean current. Everyone involved made it to shore safely and it looks like Henry was ready to test out his swimming skills again yesterday. He had help from Martin in the water while Heidi snapped pictures and cheered him on from dry land. Heidi and her family have been in Hawaii since last week, hitting the beach and soaking up the sun, and despite their near drowning experience, also celebrated Easter with an egg hunt. They've since wrapped up their vacation and arrived back in LA last night.
