Can parenting overcome peer pressure?

Peer pressure is a prevalent problem these days. It's not just about bad habits being cultivated but also faltering in things due to undue pressure.

yes, parenting effect the peer pressure. I suggest Parents should look after their children in peer age normally as a friend

I fully agree that peer pressure does effect parenting because it is human nature to get influenced or inspired by others. It might be impossible to nullify it but for sure it can be minimized to a great extent by conscious parenting. The bond and trust between a parent and child is formed from a very young age. So how you have bonded in initial years will reflect when your child is a teen. If you have pushed him and compared him to others , you have damaged his self esteem and his trust and bond with you. If the child feels trusted and accepted, he trusts and accepts you as a loving authority. Children also feel betrayed and loose their trust in their parents when they sense a contradiction inn your preaching and what you live. They sense you under your skin. For a teenage, the mere expectation is truthfulness. So if had a strong bonding in your early years, You can sail through this easily. But not to forget, parents are not the only influence on a child's life and so peer pressure can not be fully nullified. Parents have to deal with it reasonably taking their child in confidence 

I tend to think that peer pressure is always present at any stage if life but for teenagers , it adds on more pressure because of their inexperience , and thereby their inability to handle it. Here communication with their parents really helps them ..

Of course, the parents can overcome peer pressure, especially of the negative kind. But to do that the parents themselves need to work really hard and take full efforts which I see most complaining parents not willing to do. Many parents keep whining about how their children will eat only junk food and not home food, but they do not take efforts to provide their children with similar healthy choices in their own homes. Just telling a kid, especially teenager to not eat junk food will not help. He is at a stage where he is views everything his parents do or tell with suspicions. So communication should be worked upon and once that is achieved the parents can take time to sit with children and explain the pros and cons of all the things that are desirable to children. Explain the negative implications of those things and how they stand to lose in the long term. That way, children will listen and more importantly respond positively.
Also, tendency of most parents is to treat their kids as if they are little children and unable to take decision. Which is wrong. Present them with choices, both good and bad, explaining the implications and consequences of both types and allow them to make decision. In large proportions, when they are able to choose, they will certainly make the right choice.

Peer pressure must be there in limits. If the pressure is more, the child becomes a morose. If it is otherwise, the child there is every possibility of getting addicted to many bad practices including drug addiction
