Your son's sensitivity, empathy, and generosity are wonderful qualities that will serve him well in life, while your daughter's strong will, determination, and cleverness, although potentially leading to some head-butting as she grows, will also be great strengths. It's a profound moment when you realize your children are their own people, with traits distinct from your own, and that while shaped by your love and guidance, they come into this world with their own inherent nature.
