8 year old suddenly being nasty

[ddgm]

Hi
just need to know if any body else has similar expereience i have an eight year old ds who until 3 months ago was wonderful loving and caring, However since then he has turned into a moody nasty child telling me he hates me all the time and even tonight for the first time ever pushing me.
He has older brother and sisters who have never been like this even though we are half way through the teen age years anybody got any ideas he has always been so nice before, only seems to happen with me.

My ds1 can be like this as well, although it's not limited to me: nastiness particularly aimed at ds2, but stroppy and disrespectful to me and dp.

I usually think that if he's behaving like that there must be a reason (e.g. when he was in Yr 1 he started being very disobedient but it turned out he was being bullied). However, at the moment it doesn't seem that anything else is going on - he's very happy at school and the teacher says he's polite and well behaved there. My sister has reminded me that when her daughter was a similar age she went through a similar stage, so maybe it's something that some kids do go through.

It's hard to deal with, especially if it seems to go on and on. I try to remind him that I love him, but I won't put up with that behaviour. At times I have had to remove him from the room because he's being horrible to either me or ds1. I try to make sure he notices when he's being wellbehaved - at times I have a book for the end of the day to write what ds1 or ds2 have done that was really good. Otherwise it's easy to focus on the negative behaviour. Can't really give any other advice but definitely offering my sympathy.

Thanks for your responce
Just happy to know its not just me going through something like this it is such a shock when all my other children have got to late teens relativley "paddy Free"
He is not a school today cos of the voting but i am going to speak to his teacher tomorrow but am sure she will say the same as ever that he is a wonderful polite child for her it seems to be just a me issue.
The only good thing i have noticed is it seems to be limited to once a week, i know that doesnt sound very often but it sesms to come round really fast
again thanks so much for your responce
