The biggest thing with teenagers is patience and lots of it. How can someone be so sweet one minute and so rude the next. Anyway this is what have done with our teenagers. There is a chore list on the refridgerator for all of the kids and has a list of what each is responsible for. I do not remind them if it isn't done by a set time then they don't get marked off for it. Come Friday when it is time for allowance anydays they have done and done right they get $4 for the day if they didn't do it then they owe me $4 because I had to go behind them and do it. After a few weeks of no allowance and being in debt to us they started to get the hint. I do not pay for movies, games anything like that that is what their allowance is for and if they can't earn the money then I am not going to hand it out to them. When it came to their rooms I never said a word to them nor did I go in them, if they didn't clean them and get their laundry out then that was their problem when they ran out of clean clothes, if they asked for a ffriend to come over I opened their door and if it wasn't clean no company first time the oldest ran out of clothes she realized I was serious. When it came to school we have one that has always been an honor student and the other two could care less. The 15 year old thinks if she gets D's she did good because ';I didn't fail at least'; We started the reward system and punishment. We went to their teachers and got their help and now anytime their is a test if they make lower than a C on it they have to bring it home and have us sign it. Everytime we get a paper to sign that is one week of no t.v, stereo, computer, video games, cell phone, phone or anything else. On report cards we set it up for every A they get $10 and every B $5........nothing for C's............if they get a D they owe us $5 and go two weeks with no privledges and if they get a F then they owe us $10 and they loose all privledges until we have proof that the grades are back up. The 15 year old was not allowed to get her driving permit when she turned 15 until she could be responsible enough to make decent grades in school. As far as sneaking around we haven't had that issue YET but when and if we do I would handle it if I caught them then no privledges for a week for the first time and add a week everytime it happened. No matter what you do expect to hear a lot of that ain't fair and that's stupid, I think that are our kids favorite words but if you make a plan and stick to it they will learn you are serious and what they get and what they can do is up to them. Even at 13 they need to learn about the consequences of their actions. We set down with our 15 year old last month and explained to her that not getting an education would only hurt her and working for minimum wage wouldn't be fun and to show her we used the monopoly money and gave her what she would make each week for working 40 hours at minimum wage, charged her rent, for food everything..........within a week she saw what we meant when she was broke and still had three weeks to go till ';payday';. Yes this was on Cosby but hey it worked and she is trying harder this year between that and the punishment/reward system.Any good advice on teens?
if the chores are done half *** then make her do it again ,until she does it right .make her show you her work every day [school work] if need to go to class with her and being a sneak well i would just spy on her more often .hope this helps
Great question and I have teens and know what you are going through. I just take it day by day and just try each day to make that day better than the day before. This does remind me that a few years ago when the parents of teens went on strike. They set up a tent in the driveway and refused to go into the home to do anything for the teen. As parents we thought this was a great idea until each day we saw the teens pass up their parents in the driveway and went into the house as if they did not have a care in the world. They kept the house in a mess and it did not bother them one bit that their parents were living on the driveway.Many of the teens today have this ';live for today'; attitude and it is really just sad. As parents we just have to do our best and pray everything turns out OK.
Set rules and stick to them. Whatever your parenting beliefs are, develop a plan and keep it consistent. My mom was constantly telling my brother, ';One more bad grade and you'll get your computer taken away!'; But, two, three bad grades later, he still had his privleges. When kids know you're serious, they will take your threats seriously. Also, be sure to celebrate success.
The only thing I found that truly works for the grades is a punishment %26amp; reward system. My daughter has a binder reminder that she logs her homework in and I require her to have the teacher to sign it. When she doesn't I take privileges away. TV, Music, Computer Games, Phone. The privilges are lost until the she gets caught up with signatures. For every week that she has perfect signatures she earns her ';pay'; $5.00. At report card time she earns $15 for an A, $10 for a B, $5 for a C - $0 for D and any F's she loses the money for her best grade. This only applies to core subjects -PE and Band do not count. You can set your own payscale. I have found that since I started using this her grades went from C and D to A and B. It took work on my part to to ensure I helped her be organized (folders for each class) and time as well I set aside time to look at her back pack at least 2 per week and I check her binder reminder daily.
