What beautiful blessings you have!
When you have children, noise in the home is normal. You have to get used to it because it's the sound of joy in the home.
There may be difficult moments that are unpleasant to hear, and you may wish for solitude to knock on your door while you hand them the phone, but keep in mind that you are pushing them away from you.
It is not easy to restrict digital technology because children fly, but it is up to us as parents to set limits on each tool for health and respect.
Good luck with your recommendations. You are in time, because every child can be fixed, but once they are adults, there is no turning back.
Greetings and blessings.
Best regards.
