Umbraco 7.5.11 and Forms 4.4.3

I have a simple form using a single DatePicker field. I have all of the JS files at the bottom of the page, so have made the alteration to InsertUmbracoForm.cshtml as detailed here https://our.umbraco.org/documentation/Add-ons/UmbracoForms/Developer/Rendering-Scripts/

I have put @Umbraco.RenderMacro("FormsRenderScripts") at the very bottom, just before the tag.

When the page containing the form loads I get the following error:

Uncaught ReferenceError: $ is not defined

The problem is that the JS script from the DatePicker.cshtml file is added to the page where the form is positioned, but jQuery has not been loaded yet (all includes are at the bottom of the page).

Is there a way to fix this, other than putting my JS includes at the top of the page and removing the alteration to InsertUmbracoForm.cshtml?
