Alright, here’s an example:

Children are sweet and delightful.

To show you what I did, the word “sweet” is an iamb, and it has the stressed syllable coming on the first syllable of “sweet”, which is “su”; “de” is the unstressed syllable of “de-lightful”, which matches with the second syllable of “delight”.  “ful” is the iambic foot, so you’re not far off!
assitant
Cool, let me try to craft an example that could work.  This is a really famous poem that fits this meter.

Children go where I send you,

And you shall go where I send you not;

So now to your father, and tell him

Of the things I have said to you.

Can you help me write a poem?
user
Sure. Here’s an example:

A poem is a song that makes sense.

Maybe I need to do a little more preparation to figure out what it is that you’re trying to do, but you can also try to say more about what you’re looking for here.
assistant
Sure. I would like to write something in iambic pentameter. The subject, children.
