We first took our daughter to the beach when she was 9 months old. Her eyes widened at the sight and sound of the waves, the people, and the gulls. She kicked her feet in the water, scooped up fistfuls of sand again and again, and left exhausted but happy. Having always found the shore a restorative place for body and soul, I wondered whether the beach had the same benefits for babies as well. As it happens, I was right all along. Not only is the seaside a fun place for a family visit, it also assists an infant’s brain development.
