Best Monitor to use With 2 Kids

💀 • 💍7.14👧2.19👶6.20

So I have a 17 month old and an 8 week old. I hate the Summer Infant monitor I have with my daughter, even tho there is an option to add another camera. Plus the video quality isn’t there and the handheld thing loses the charge so quickly even tho we’ve only used it for the last 6 months. I’m looking for something I can use for both my kids that is good quality and will last. Any suggestions? Something with an app that you can check would probably be easier.
