McDonald’s just can’t stop riding the breakfast wave that has boosted the company’s sales and brought customers back through its doors, it seems: after scoring with all-day breakfast, the fast food chain is now toying with the idea of offering Happy Meals in the morning hours.

On Monday, the chain will begin testing a breakfast Happy Meal at 73 locations in the Tulsa area, USA Today reports (warning: link contains video that auto plays).

The meals will feature more kid-focused items than the options on the adult menu, with a choice between two McGriddles (just the two maple-flavored cakes, not a sandwich like the adults get) or a new egg and cheese McMuffin that comes without Canadian bacon. Side options include apple slices or yogurt (items McDonald’s introduced to Happy Meals in 2014), and some restaurants will also offer hash browns.

The addition of breakfast would be the first major new choice for the Happy Meal in more than three decades, a spokesperson tells USA Today.

“All day breakfast has really been a big hit with our customers, and that started from our customers telling us this is what they wanted,” says Pam Williams, a director of innovation at McDonald’s USA. “Since the launch of all day breakfast, more of our customers have been reaching out to us and asking us for these choices for their kids In the Happy Meals.”

If the tests prove successful, McDonald’s could introduce breakfast Happy Meals nationwide next year.
