Multiple routers for meant devices.

Just wondering if it's possible to use 2 wireless routers instead of one to "split the load" of 30+ devices? Because of the amount of devices, communication between devices (smart devices, game system, TV) I was wondering if there's a way to add another Wi-Fi either in line or separate to share some of the traffic load? Not sure if this is even possible just have 2 Netgear routers and figured I'd start here, thanks In advance
