I wish I had a magic cure, but honestly I think it helps to know each of us are not the only parents who deal with this.
There are times where l just want to cry because the kids are so rude and smart alecky. Sometimes I feel like nothing more than a glorified babysitter.
My gang are 15 (male), 15 (female), 12 (female) and 10 (male)
I have gotten into shouting matches...smacked them in the mouth

( I apologized later) and complain and whine to my poor husband. He never seems to have this problem.
I am grateful to have such a wonderful man who supports me but I still deal with this garbage almost daily so I can SO relate to you.
I have really begun to pray about the whole situation and have tried to find ways to connect with them.
Good luck
