How do I handle my siblings?

First off you have to realize siblings WILL annoy the hell out of you. You cannot let it get to you at the point of ridiculous temper, remember you were once three and went through the "no" phase so don't pay it much heed. They do obnoxious things to get attention out of you and if you react they get what they want, we're talking about children here. You'll have to gradually learn patience and to BE A GOOD role model to your younger siblings because somedays they will look up to their older sister.

well dont hit them...my nephews like that always saying no etc...but what i do is, i say you wont get, for e.g. a chocolate if you dont pick your toys off the floor...you should do that, be nice and calm with them and they will do the same also say stuff like if you do this or that you will get a reward or something....with the temper control it...when your mad sit down if sitting down does not work the lye down if none of them work then drink a glass of water to calm yourself....and take some time out in the day or night and just meditate and picture yourself being free and in peace trust me it works...

dealing with siblings is hard thats for sure! When you get so frustrated and mad, is it possible for you to just get away for a while? lock yourself in your room or take a walk? Talk to your parents, share with them your frustrations. Tell them you would like some time away. Also, talk to them about your sibling saying No all the time and find out how they handle it and ask them how they want you to handle it. With little kids, it's best to be consistent with the rules.
Hang in there!!!!!!

Do you think the Autism is a problem? It sounds like the usual conflict between siblings at any age. Just remind yourself that they love you and you love them every time you let them get at your feelings. There are specialists in Autism that can help you and your folks.

Go to the book store and get a development book on the ages of your siblings. Being the oldest gives you great responsibilities and you will carry that for the rest of your life. Imagine having 5 sisters in different ages, two older and three younger. When you are able to deal with your siblings correctly you will not have any problems with dealing with people in general. Best of luck to you.

Practice your patience with your sibs now, because it will pay huge dividends for you in later life. Believe it or not, once day these 3 little people will be all grown up and will be among your best friends. Learning to deal with them will teach social skills you will use in dealing with all kinds of people. There are many people in this world like your 3-year-old sister in that they never outgrew the "no" phase. Some of them are 60 years old.

Don't hit them. There is only so much reasoning you can do with a 3-year-old. They understand action. Tell her what will happen if she does not comply with your request to stop her behavior, then DO IT. You have to be consist and you have to make the consequence believable. Don't tell her you'll send her to China or something because even she knows that won't happen. Tell her everyone else will get to watch TV, or a video, or whatever, but she will not be able to join you, or that she has to sit with her face to the wall for 2 minutes - eternity for a 3-year-old.

You can do this - I was the youngest in my family and I had a ton of nieces and nephews to deal with. Most of the time, kids are great as long as you keep them busy, the problems start when they get bored or frustrated.

Treat people the way you would want people to treat you.
