Do you allow your kids to play gadgets/ipads often? If so, for how long?

I'm not proud of it, but we're working on it! I try my best not to give my son any screen time, but sometimes it's the only thing that appeases him because my parents are the kind who throws him YouTube and watches their own shows/mobile games - my parents even have a phone specifically just for him to watch his shows, but I have been hiding it so that they aren't able to give it to him. He's 25 months old now, and it's fine on days that he goes to childcare - we keep our phones away when he comes home so he doesn't see it, and we engage in play time with him. But on days that he doesn't have school or when he's sick, he has a radar for mobile phones. I use my phone to do work and he understands, but as soon as he sees my parents' phone lying around/in their hands, he'd start fussing for shows and watches for the next hour or two. It was a lot worse before, hence I said we're working on it - and being in childcare now helps to engage him in better play even at home :)
