While each hut housed a squad of twelve enlisted soldiers, sometimes soldiers' families joined them to share that space as well. Throughout the encampment period, Mary Ludwig Hays and approximately 250–400 other women had followed their soldier husbands or sweethearts to Valley Forge, sometimes with children in tow. Washington once wrote that "the multitude of women in particular, especially those who are pregnant, or have children, are a clog upon every movement." Yet women on the whole proved invaluable, whether on the march or at an encampment like Valley Forge. They often earned income either by laundering clothes or by nursing troops, which kept soldiers cleaner and healthier. In turn, this made the troops appear more professional and disciplined.
