5 children just me home none will go to sleep

Well myself my husband and my children and my sisters 2 little ones all went to something called Raleigh days today, as we were so happy to be joined by 2 of my sister in laws, and 2 more of my nieces and 1 of my nephews. Of course there was a falling out with my husband and my sister in law, but my husband is very nosey and very mouthy, he thinks he has to have say in what everyone does. I am just glad that I didnt get involved or brought into the middle of it because I love spending time with my in laws. They are very special to me and very important to me. But the children did have fun as well as myself. But now I have 5 children my 3 little ones and my two youngest nieces, and my husband is at work, and none of the children want to go to sleep. They are very energized now, and well that makes it fun for me. Then it doesnt help that I have a huge fear going on right now. In 2 weeks my 2 sons will be going to spend the weekend with their real "mother" and I use "mother" very loosly with her because she hasnt tried to see them in over a year. I have many fears about that weekend. First and formost is my youngest sons medical problems he has very bad asthma and well he is on a nebulizar and well they want to take him camping and will be sleeping in a tent with no electicity so if he has an asthma attack how are they going to give him his treatment. Second is the part of her not seeing them in a year, I dont know how they are going to act with her and if my youngest will even want to leave with her, he was so young when everything went on between their father and their mother and he really only knows of me as mommy. The only females that have ever always been there or taken care of him for as long as they have been in his life is myself and my sister in law Angie. Another thing is I know she has not been one to watch over children like they should be and they are going to be around water, neither one knows how to swim. My oldest son he has some authority problems already because of everything that he has been through already and his mother is a main part of that, I am afraid that him being with her will make it worse. Like any other mother/step mother, all they want is for their children to be happy and safe. I know my children are very happy and safe with the ones they are around here, but I am not sure on how safe they will be with their real "mother". And that scares me to death. Well enough about that. Tomorrow is going to be a very busy day, my niece Krystina is graduating high school tomorrow, and I am so very proud of her. I hope all my nieces and nephews that have not yet graduated high school, does graduate. For I did not graduate high school, and I regreat that everyday of my life and I never want any of them to have to live with that regreat like I have to. Not only does my niece graduate high school, but my oldest niece Susan, her husband Matt, and their precious angel Katelynn will be here and I love getting to see them when I can for they do not live that close to us. Well all kids cept for the youngest have gone to sleep now, so I believe that I wil be going to get her to sleep and try and go to sleep myself now.
