However, I don't believe it's possible to both foster the growth of a child as an independent eventual adult and protect them from all trauma. Life throws trauma at you unexpectedly even if things are generally good. Too much protection can stifle growth. Not enough can, obviously, cut it tragically short
I think once guide rails to keep the kids alive are established, the best goal to pursue is equipping them to heal in a healthy way when they get hurt. Trauma happens, but it's the scars it leaves when healing is unsupported and processing is messy which really make for fucked up adults, when trauma is what's fucking us up, IMO.
That said, breaking generational cycles of abuse is definitely about identifying trauma that is caused by how we were raised, and deciding not to continue that tradition. We might fuck up our kids (we ain't perfect), but at least we won't do it the way our parents fucked us up. Definitely not without even thinking about how things came to be the way they are.
