Screen time for babies, toddlers and kids

Thanks for this topic here. I'm so much glad to know more about this screen time. I also have a baby who is 3.5 years old now. He is so much interested in watching cartoons. I know it's not a good idea to give him an Android phone. Because this might damage his brain and eyes at the same time. So I already installed a screen mirror https://www.imyfone.com/screen-mirror/ I think this might be helpful for a kids and can minimize the risk. Let me know your thought.
