Help! My teenager won't accept rules and boundaries :(
To me it doesn't sound like you have set boundries but more punishments as they did not exist prior to your daughter's behaviour and maybe that is how she is viewing them and why she is rebelling? have you tried getting her to provide the boundries? and/or providing her with a way to get the boundries relaxed?
on a techical note some routers / internet gateways allow you to set access schedules so it only broadcasts a wireless signal during certain times and allows you to block certain devices. So, she can have her mobile and laptop but won't be able to connect up to your internet (you and your husbands internet) that you choose to share with her.
with Telstra i believe they also have a service called "Telstra Mobile Protect" which allows you to restrict call and SMS activity and set time restrictions. I think most of the providers (optus / vodafone) would have something similar. I assume you pay for her mobile? if so then tell her if she wants you to continue to pay for the mobile then she has to respect your boundaries if she doesn't want to respect them then she will need to pay for her mobile usage herself.
full disclosure, I don't have kids but, based on my past experience working with children and studies in psychology, that is what i would be trying / looking into.
Oh the fun of teens. I know what your going through. I have a 14 year old son. In Queensland schools laptops/tablets are issued so if thats the case probably not a good idea to take it away. Something we do when things get out of hand is put a old cord on our internet connection that doesnt work properly so he thinks the net is playing up. Sneaky i know but he gets frustrated and gives up. If shes not allready put her on a prepay phone or her data bill will go crazy.
Not sure what state your in but kids can get a part time from 14 in alot of places.
Its good for them. I keep my son pretty busy with Army cadets and working at a local takeaway. The late nights get crazy but its amazing what a not working properly charger can change.
