At one month my Bean was weeny and light,
All wrinkled and hairy and crying at night.
At two months his smile was beginning to show,
and his eyes seeing people he wanted to know.
At three months his arms and his legs waved about,
accompanied well with a squeak and a shout.
Now at four months his giggles just fill me with joy,
He's simply delicious, my four month old boy.
