Children lines in palmistry

When I started palmistry , I was going through different books , according to all of them the vertical line on the side of little finger.  show the children on person hand. But these line are so faint most of the time.  We cannot judge them properly.  

They are so small and most of the time invisible you cannot get the clear picture. Upto some extent it may be right. Because we cannot read those line from almost behind the hand and side of the palm.

later on I realize that it is not the only way to find the truth about children. 

1. complete head line. if it good ,healthy and long it show you have children. Curvature of this line show the male or female child.  most of the time, I saw that people having straight head line with no downwards end of head line show person might have female children.  You can say his first child will be female. All these thing I have noticed on husband hand. 

2. Complete head line with slight downwards in the end reflect the first male child most of cases.  Nature play a role if head have little curve in the mid of line.  Nature will provide male child first.  if hand show the practical person his second child will be female. 

3. under the thumb if there is chain on last phalange it again show the male child. But it does not assure about other information.

4. length and curvature of mind line play the crucial role in a person life regarding his children.  If there is any island on the mind line then it may lead to children life then one or first child will be emotional in nature. he need support. It depends on how big the island on mind line.   But the island on head line also reflect the mental tension in person's life. 

5. healthy long mind line play a crucial part in children prediction. Small and little bit short head line show person will get child late .. it also show less number of children ...
