I sing this to my kids every night. My Mum sang it to me and her Mum sang it to her, and her Mum before that :)

Upon a seat one day a little maid sat knitting,
There eating bread and jam a boy was also sitting,
He sat and munched away and never thought she spied him
'Till with a longing sigh she came and sat beside him.
Taking up his sticky hand she bowed her curly head
And roguish eyes to his surprise smiled at him as she said

Dear little jammy face, I love you so
I wish I were your sweetheart or your Mammy
Just what the reason is, I'm sure I don't know
Unless it is because your face is jammy.

Pray won't you let me take a bite of what you're eating?
I do like bread and jam the maiden kept repeating
I'm sorry little girl, the boy said softly sighing,
All of it's gone I fear, then saw that she was crying.
Don't cry little girl and then perhaps I will let you kiss me twice!
The little maiden dried her eyes and said "That would be nice."

There on the seat that day, they vowed that they would marry
When they were old enough, and sure they did not tarry
Now there's another little boy and he's just the sweetest thing
And every night on Mummy's lap he loves to hear her sing

Dear little jammy face I love you so
You're just the very image of your Daddy,
I loved your Daddy dear, long, long ago
And all because his little face was jammy.
