His child destroys us...?

Being the youngest, she probably feels it ifficult to adapt to a step Mom and surroundings, so is therefore insecure. In addition, she is aware she can control the situation and/or events by creating a fuss.

Sadly the only person who can address this problem is her Dad, but he has to recognise she will play him up if he lets her.

maybe you should take her to a psychiatrist if shes having problems like that

I have 5 brothers and 4 sisters and I will tell you -- 3-year-old is NOT in charge. If we want to go to the beach we go to the beach and if 3-year-old nephew complains, 3-year-old stays home with mom. If 6-year-old wants to sit and whine, you put in earplugs and let 6-year-old sit and cry all night. If she does not want to eat your dinner you get her those single-serve cups of Mac and cheese and you make dinner for everybody else and she gets a mac and cheese cup and if she cries, you pick up all the food and put it away and she goes to bed hungry. My dad would never let us quibble over food.If we did not eat we did not have any replacement food, so if we were hungry, we ate, and if we cried, we were sent to our room. My dad would send us to go cry and scream in the car if we were throwing any kind of fit in public or at his friend's houses. We learned in a hurry the car was no fun. If you want to go to the pool and she does not want to go, leave her at home and YOU take with you the ones who DO want to go. If YOU want to go to a restaurant and she whines, YOU go in and order food to go and bring it home and eat and enjoy it and let her cry. If YOU want to go to the park, YOU go to the park with those who want to go and crying child can stay home. It is up to YOU to take control of the rest of the family. If she is not legally your child, you are not the one responsible for making her life better, you are only a nice person in her circle of existence. She will soon watch you leave with the others and watch the fun you have without her, and if she really is as smart as you say, she will change her tune. MEANWHILE --- earplugs. Earplugs for every single person in the family who does not want to listen to her. And if she screams, her screams go nowhere. She screams only so long as people listen and react. If you are no longer hearing her screaming and no longer reacting to her screaming, and I mean, she screams, you take your conversation with another into a different room and continue your conversation as if she made no noise. You still continue to do your tasks whether or not she is screaming. If you are watching tv and she screams, you find your show on your portable device and take your entertainment out of the room and into another room and lock the door behind you. If she screams during a family program, you take her out of the room and into her room and tell her she can scream as much as she wants in her own room but she is no longer allowed to ruin everyone else's time any more. You can tell her she can come out when she is finished AND STICK TO IT. ........ YOU are the one who MUST be consistent with this new way of treating her. No more yelling, no more trying to reason with her -- that is over. You treat her like you are a cat on the sidewalk walking past the dog who barks at you every day from behind the fence.... you simply ignore the noise and keep going. If she wants to eat nothing but mashed potatoes and beany-weenies, you set them in front of her for every meal and food is no longer a choice from a menu at home. It is no longer a "Do you want this or that?" question, it is, "Here is your food and you eat it", and then you make the special food for yourself and the others. "Here is your sandwich, here is your fruit cup, here is your juice box. Eat." and then you do as you wish. If she makes a mess on the floor and refuses, you pick it up and put it in a trash bag and throw it in the trash. BELIEVE ME , when you start to refuse to respond to her demands, she will change in a hurry! I can tell you that youngest brothers and sisters are well-behaved people to this day. My own daughter has observed the bad behavior of her cousins, and now thanks me for teaching her how to behave differently! Now that she sees in others her own bad behavior, she has changed her own complaints a lot more. It CAN happen. If I can do it, so can YOU. Good luck!

DUMP him and move on..............at least, for your son's sake.

GOOD LOOCK
