Good has created parents with some special characteristics, which includes control over some tight and difficult situations.
That fact cannot be taken away from them. I guess that's why they have been called parents as all they are after is to take care of the seeds that that God has entitled them with which happens to be children.
Children on the other hand lack this special characteristic which includes the ability to control things when they get out of hand.
Parents deal with it specially simply because they have gone through all corners of life and have probably encountered such a situation or might have seen someone who encountered such a situation.
They prefer better solutions because they must have learnt from previous experience.
Now as a parent my daughter became pregnant all in the name of trying to get an admission into a university.
Of course just like everyone, we are humans and at the same time got emotions which might lead to some irrational decisions but then as a parent you can correct a wrong with a wrong as two wrongs can not make a right instead it might lead to a worse situation in the long run.
Being angry, furious and aggressive is what every parent will show because you can't as a parent try to make someone grow but the person turns the other way round bringing all your effort to the ground with just a single mistake and making you look irresponsible before the sight of other people.
A mistake that has been done can not be reversed most especially in this situation as any move to correct it might cause more harm.
I come from a Christian home and my faith will not encourage abortion as that's not what my faith teaches me, so a parent I will scold the child and let the child know that there will be delay in whatever plans she has for the future as what is suppose to be accomplished within a uear has been extended to 2 or even 3 years one year of carrying pregnancy another year for breastfeeding the baby and probably an extra year for the baby to get to a level where someone can take care of him or her.
All this process will be a big lesson to a child who chooses to go that way and the lesson will not stop with her as it will also flash on the heart of the younger ones and it will help keep them on track.
By the time she has done all these processes when you enrolled her in a school she will know nothing outside than to focus and get her things right as she wouldn't want to spend extra years achieving what she would have achieved some 2 years ago.
Don't punish them as a parent, allow karma to do his job and you will love the outcome after all has been done.
But in all Try to be a parent, do not equal yourself as parent to the children by taking some decisions that will lead every one to regret.
