Conditional Next Page?

I am creating a field trip sign up form for our school. I need the ability for a parent to select “add a child” and have it go to the next form to fill out OR click submit and have the form be finished. Is this possible?

I tried adding hide/show text, which actually worked, but if the parent doesn’t add another child the form still requires those fields (all form fields are required). So the alternative is to just add another form url.
