In one sentence, describe what the following article is about:

Let your stepchild know that you are available to talk whenever needed and be a good listener when your stepchild does come to you for a chat. Be open-minded and accepting of difference, as the child has had different experiences before you came along. Make your own preferences known without being harsh or intimidating––always explain your actions and preferences with sound reasons.  Never let the only interaction you have with your stepchild that day be yelling and screaming. You should always try to focus on the positive things they do and not always the things they are doing wrong. Keep your negative opinions of the child's biological father to yourself. Unless you're asked directly, don't bring up your opinions of him in front of the children or anyone else. If you are asked directly, be circumspect and tactful, as there is often a risk of an emotional overflow. Each parent's parenting style is different and unless the father is not taking part in parenting at all or is abusive in any way, you don't need to pass judgment. Never argue with the child's mother in front of the child. Be especially careful about making derogatory remarks about her where the child may hear. The child will be highly alert to any disharmony, mostly due to a sense of protectiveness toward the mother and holding a strong hope that this new relationship will result in creating a happy family arrangement. The child/ren will need your love and affection at all times, they will need you to be there whenever they need you, no matter what the situation. Moreover, they will need you to be the better parent at times, they will need you to stick up for them no matter what, and they will need you to give them a pass once in a while.  Be ready to listen to them and understand what they are going through or what they are trying to say. Give them your fatherly shoulder to cry on at times or even just a hug or a kiss on the forehead or just a simple "I love you".

Summary:
Communicate clearly and calmly. Be openly caring.
