No matter what kind of parents are, at certain age, they all eat goo from theuir nose, flys, almost anything

It is when they start to explore newly discovered world around them and find out what is difference between me and a dog or at least close there.
Baby brain and adult brain work quite lot differently, transition phase produces lot of amusing situations.
But I totally agree with redline, parents today don't understand responsibility of being parent, they don't understand that drinking reason out of them is bad thing because as parents they should always be available for child to give protection, care and guidance. It is job of lifetime and there is no life without child when one gets a child, still many think that they don't need to change how they live when having a child.
Then we read news, teenagers get stabbed, teenagers hang out at town as they are too afraid to stay home, 3-5 years old are seen walking alone at winter night and when child is transported to home by police parents almost ignore that incident, like there would not been anything wrong, naturally parents are too drunk to take care of even from themselves.
It would need only tiny bit of thinking before action, but today one is excepted to only act based on current emotion, that is going to be really bad thing.
There should be license for getting kids, something as challenging as commercial helicopter pilot license, but in child rising aspect.
