Oh no Shannon...we are entering the alien years!!
Una, so glad you posted. We are experiencing this as well. I really appreciate all the comments and Gaylene's experience too.
I suspect you are like we are, as a family of three, we are extremely tight. So when Master 11 starts with the attitude, moodiness, etc I find it really difficult. I don't have any answers yet but one thing I have become aware of is that our kids need us just as much at this age (despite their developing independence) as they do when they are little. Someone shared with me recently that in some ways, teens need us even more.
One way I have been connecting with M11 recently is I have been taking a more active role in his homework. (not doing it for him of course, but participating more, working with him on his spelling, tables, supporting him as he does a display for a project etc). This might sound strange but most days I am the last one home and he has done his homework (so he says) by that time. He was a little resistant but now we are really enjoying the time together. I tread carefully so I am not telling him what to do or how to do it and homework has been fun and he is seeing that is capable of more than he thinks sometimes.
We still share a love of Dr Who, so we do watch that together as well. That is something he and I share as DH isn't interested in the program.
I am finding keeping him well fed also helps with his mood and sleep seems to be really important at the moment. Given that we are pretty strict that bedtime is 8.00 p.m. and there is no mucking around.
The other thing I have noticed is that it seems to be a stage where we have had to crack down on the discipline again and not let him get away with bad behaviour, which means not backing on down and carrying through with things. Loosing access to his ipad for a week can work wonders in terms of attitude adjustment.
We also talk a lot and constantly reinforce that he can talk to us about anything and be guaranteed we are not going to freak out (well not in front of him lol). So at this stage my thoughts would be sleep, food, communicate and don't react
If it makes you feel any better, I am right there with you And I know you are an awesome mum and you will work you way through this.
