Till today, I still remember that day-the 9th Dec, 2011, our baby began to have his 1st tooth. That day, riko said, when she use spoon to give him food, she heard some light Ding-Ding sound.
She looked at his mouth carefully, a tiny white point has come out from his gum, like a small bean spout... All of us were very joyful.
But in the coming next month, he just has this single teeth, so we called it "the only child(独生子女)".
With the time passing, he has 4 teeth now. 2 are up, and 2 are low, in front of his mouth.
