People's anger should really be directed at the government, not the parents (although I get leaving the sound on is annoying). Can we all remember that no one gets parenting 100% right and giving a bit of grace never killed anyone. Tablets for kids is quite normal and a lot of parents do it; they even use tablets in schools and even some nurseries. Tablets are used for homework in some schools. There is even pressure on parents as most kids have phones/tablets and those that don't can get bullied in some cases.
If people have such issues with tablets then take it up with the government not individuals 😅 if tablets/smartphones were banned for kids under certain ages then it would be easier for parents. I don't want my baby to have a smart phone (just one of those old Nokia ones would do so I can contact her), but terrified of the day when she tells me she's the only one in her class and she feels left out, lonely, and is losing friendships because of it. Or worse being teased or bullied. What will I do then? I don't know is the answer, I just hope smart phones get banned for kids before she is that age.
