So, where to start... I am a BM of 2, SM of 1. My BD is 3, BS is 10months and SS is 5. I have been in the picture since my SS turned 2. Not much changes in 3 years. I have always been the bad guy because I want my children to all have manners, respect, and because I keep them on a pretty regular schedule. My SS lives with us primarily and sometimes sees his BM. She recently had another baby, lives on welfare 100% and child support for the new baby, and doesn't work or drive. She tells me all the time that when he is there she lets him get away with a lot because she missed him and doesn't want to have to enforce rules because then they can't enjoy their time together if he is in time out the whole time. She buys him everything he asks for and he has her 100% undivided attention the whole time she is there. I am at stay at home mom currently and my husband works very hard and is rarely home between his FT job and the Army. I do everything for all my kids and love it all. However, it is a constant battle with my SS because even after 3 years he has no matters, and thinks that at 5 y.o he can talk back to me about everything and get away with it. He claims he misbehaves because I am mean and never let him do anything. He tells his BM all sorts of stories about things that I supposedly do, like locking him in his room all day and never letting him out...ok a 5 minute time out and being told to pick up your toys and not scream while doing it, or to stay in his room until he can be done screaming is what I do. My 3 y.r BD has the best manners of any little girl, and yes she has her moments with temper tantrums but atleast is isn't every morning. I know he is lashing out because his BM doesn't call him or see him very often, but I have no idea what to do and I feel like I am going crazy. We have tried everything and nothing seems to bother him, no punishment in the world that we have tried even affects him in the least...Any suggestions? I would appreciate anything..
