The meaning is
The love between a mother and daughter is like nothing else in the world. It knows no conditions. It knows no limits. It never fades, never diminishes — it always stays. It stays through arguments, disagreements, heartbreaks and tears. It stays through laughter, accomplishments, milestones and fears. Thank you for loving me the way that you do. Thank you for being by my side. Thank you for giving my heart a forever home. You are my sunshine — radiating brightness and warmth into my life. You are the light that I can always count on. You make even the darkest days seem bright. No matter where we go, or what we do — we will always have each other. Because a love like ours lights the whole sky. A love like ours burns brighter than everything around us. A love like ours is forever. The world is incomplete without the sun — as I am incomplete without you. You are my sunshine.
