The question "when should a parent should give the children privacy"? Though I am yet to be a mother but I can share my little advice as an elder sister that has trained her younger ones like her own children and from experience I witness in people's ways of parenting. Every parent loves their children,they do not want them experience the consequences they had to experience due to that lack of knowledge and mistakes they make when they were younger too. Parents will likely to be blamed for their child misbehavior and how he or she turned out to be, so they want to try their very best to see them come out and make them proud.
If we should be true to ourselves, parents invading their children privacy is normal and productive, children needs a nosy parents,these children believe they are now matured to think and do things in their own but they aren't. Parents monitoring every move of her child is nothing bad at all, it's a very good one . The fear of" my parents will find out and will be very disappointed in me" alone will make them out their actions together and desist from doing what's bad.
They need someone to pinpoint what they have done that is wrong but the mistake a parent can do is having "lack of good communication" Some parents only way of training their child is always telling them they didn't do enough,only complain when they are wrong but never praise them when they do something nice. Being nosy into your children's life is ok but then the way you approach issues with them is what matters most .
This approach can vary according to their age , a teenager needs more clearer explanation and enlightened more than putting them to blame all the time. You have to be careful of words to use on them by that stage , they can resent you for the rest of their life with some words you think you said because you want them to do better. If you can approach matter with them well, they won't hold you invading their privacy. You saw a text about love on your child phone and the next thing is shouting and disgracing your child of this bad behavior she did, No! That's a really bad approach, why most teenagers recent their parents and decide they would that theat things they do not want since they had tell the whole neighbors already, everyone now knows,there is no freak about it again, talking form experience.
A good approach is calling your child alone with you with a cool voice , enlighten her on how bad a love life who ruin someone of her or his age, telling him or her the advantages of focusing on more better things and that love can can come later, then the love will be opened and no one will be able to gossip about it because she is of age and has what she should have. You didn't say you saw it but she will feel what you said and go to make amendment of what she had done ✅ that's a good approach.
Not all the time should it be on blaming and telling them they aren't making you proud, find a problem with them, come up with a solution with them even if you are going to scold them ,let them understand the other way to go about that act that will be accepted than that.
For me, no age for giving privacy but there should be a good approach to handle them according to their age.
