Diane's POV
I woke up to the sound of soft knocking on my room door, followed by Joan's familiar voice singing "Happy Birthday" in her slightly off-key but enthusiastic way. My heart swelled as I heard my mother's voice joining in, creating a beautiful harmony that filled the quiet morning air.
"Happy birthday to you, happy birthday to you, happy birthday dear Diane, happy birthday to you!"
I couldn't help but smile as I sat up in bed, one hand instinctively moving to my rounded belly where the twins were already stirring, as if they too could sense the special energy of the day.
"Come in," I called softly, and Joan practically bounced through the door with my mother close behind, both wearing bright smiles and carrying steaming cups of what smelled like my favorite herbal tea.
