The First Tooth

Through the house what busy joy,
Just because the infant boy
Has a tiny tooth to show!

I have got a double row,
All as white, and all as small;
Yet no one cares for mine at all.

He can say but half a word,
Yet that single sound`s preferred
To all the words that I can say
In the longest summer day.

He cannot walk, yet if he put
With mimic motion out his foot,
As if he thought he were advancing,
It`s prized more than my best dancing.
