In the video, 3-year-old Stella held her new baby sister, Sophia.

Stella asked her mom if it was Sophia’s birthday, because she was born that day.

Allisa told Stella that it was indeed the baby’s birthday.

Stella then asked her mom, “Can we sing “Happy Birthday” to her?”

The little girl then sang to her new sister and gave her a kiss.

Allisa wrote in the video’s caption, “Be right back, my heart is currently exploding because, how is she so sweet?”
