Every parent wants to protect their baby — but what if the window to prevent lifelong allergies is smaller than anyone realized? Scientists have discovered that a newborn's immune system doesn't just work differently from an adult's; it's actually wired to overreact in ways that can set the stage for eczema and allergies before you even know it's happening.
