It's great hearing this fact about this effect, like I did had an idea but not a depth knowledge about it!
"Good" Parenting is actually a very critical and important thing which sets up the mental health of the child because whatever the child feels so he/she will opt the situation upto.
Sometimes I do have seen people making up good assumptions and plans for the children but they don't work and it's really a serious situation for them, they do get stressed and anxious, some get angry and that's how it effects the child, one really need to be comfortable with their partner and make us good outcomes about the situation which has arrived, because there's no idea about the what's going to happen the next moment.
So giving up a good parenthood to the child first needs a good compatibility within the parents.!
