Top level Nav Dropdowns and/or Pages

my challenge is to have top-level navigation items that have subnavigation and are also clickable as they are the parent pages to the sub nav

So let's say top navigation items; One, Two and Three. Subnavigation items for One are 1.1, 1.2, 1.3

Now, on desktop I know how I would handle this - show the user the sub nav on hover and still allow the user to click the top level nav but on mobile this gets a little tricky because we don't have the hover effect.

I thought about having a little chevron or visual queue next to the top-level navigation item that would toggle the display of the subnav on mobile but I think the user would still instinctively tap the word expecting the same behaviour

Sorry if that was a bit of a convoluted description. Thanks in advance for any help!
