Name this poem

[orphelia]

I remeber reading a poem about parenthood. It was very short, only several lines, and was about sacrifices a mother makes for her children.

It includes a line 'this is my life, pass it on'.

I'm fairly sure it was written by a contemporary English poet.
Any help gratefully appreciated.

Here it is:

The Mother - by Anne Stevenson

of course I love them, they are my children.
That is my daughter and this my son.
And this is my life I give them to please them.
It has never been used. keep it safe, pass it on.
