Birth
I do not intend to spend much time on this although, especially for the mother, this is obviously a very important aspect of raising your children. But it is something that I have very limited experience with and have not researched much so I will leave expert advice on this to others more qualified.
Giving birth is supposed to be a natural process, and the majority of women go through birth without any complications. If you would like some useful information on preparing for your first childbirth there is a link at the end of the book. here
But whether or not the birth of your child is complication free or a near total disaster, as ours was, it does not seem to have any bearing on the later development of your child. But, just to ensure yours is as stress free as possible best make sure you engage the services of a good doctor to oversee your preparation for the birth and to be available on the day to handle complications if they arise.
I will never forget the words of the doctor chosen to manage the birth of our first born. To everyone else the birth appeared to be overdue, but our doctor did not seem overly concerned. But finally the birth did have to be induced, which he did, and then he left my wife in the hospital while he went off somewhere else for a few hours. When he came back and saw the trouble my wife was in, his exact words to me were "I cannot do this" and so the gynaecologist who was considered the best in our area was called in. I won't describe what followed, but both my wife and daughter survived and the trauma of the birth clearly had no after effects on my daughter, except for having to spend two weeks in a humidicrib.
Make sure your doctor is qualified and experienced. We don't pay them to supervise the easy births that anyone could manage. We pay them to be there to professionally manage and solve problems if and when they occur.
