Many new parents don't realize what natural swimmers their babies are.Until around 6 months, babies placed in water tummy-side down will move their arms and legs in a swimming motion. When the swimming reflex and the dive reflex are both engaged, a baby can then turn on their innate swimming ability. Researchers studying the dive reflex in babies found thatnone of them inhaled water or choked when they were under water.The babies didn't seem worried about the next dive at all. In fact, some seemed eager to dive again!
