I suppose it would have to do with where the mind of the parent is. If the parent had the child thinking that the child will love the parent without conditions, then the parent got what she expected. Now in reality, there is not a child living that doesn't have expectations when born. Where is my bottle? When are you going to change me? I need to be burped again? Is the bath now or why do I have to take a bath? All of this has to be done. To the mature parent that planned to have children, she knows of all of these things that she has to do and over the years she has reconciled herself to believe when she is finished and this child is of age, she will reap the harvest of all of that hard work. The child grows up and moves out the house to be a successful adult. She loves the child with the condition that he/she will grow up with a plan of their own to be independent of the parent.
