From my point of view, it builds trust.
i have children of all ages, two are adults. Yeah, they have had issues at work and at uni. They call me to talk about it, because they know they can. I will talk it though with them, bitch about whoever has been an arsehole with them, it makes them feel better and then they carry on. They haven’t needed rescuing, but all my children know they can come home, no questions asked, any time, any age, I’m here.
My parents? God, I could never. It would have been my fault, I wasn’t trying hard enough, I should be more resilient (that was their buzzword), I shouldn’t be so sensitive. I stuck out an abusive relationship due to that.
I’m glad my adult kids can call me after a tough week, have a moan, have a laugh about it, feel better and carry on. That was built when they were younger and me saying “if you don’t like it, I’m there, I’ll come and take you home.” My children are too independent to be honest, they are both off doing amazing things, thousands of miles away! Knowing I would come get them if they needed me didn’t ruin them, it gave them confidence.
I know so many people will disagree, but knowing that I would come and get them when they were younger, from situations they were unhappy with is what built thier confidence.
