That smile is not only an expression of joy, but also a sign of the development and bond of family affection. In that moment, all the worries and fatigue of sleepless nights seemed to disappear, giving way to full happiness and hope. A baby’s innocent, pure smile is a priceless gift that everyone feels lucky to witness.
