No one listens to me about my twins HELP

C.L.S • 😃
Please I need advice. So my husband and I have been living overseas and I came to my country to have the babies and live. Well we are building a house and it's taking a lot longer than it should be. So I'm living at my parents house while my husband went back to us country. I know it sounds great but it's been a complete nightmare. Everytime I tell them nicely to do something they think they are right and do the opposite. For example my mother keeps putting blankets on them and my little one get them over her head, I told my mother to stop but she won't and yes they are over heated because the ac is also broken in the upstairs area. Also I tell them at night please don't play and bounce them around and leave the lights bright on in the room when they help me feed them because they will be up all night and they don't so I'm up all night alone with two screaming kids. Then they keep feeding them whenever so they both can't nap at all and her super gassy fussy and cranky and I feel so bad because I get so frustrated because of their nonstop crying and don't sleep all day. I can't move out because it's just not good at moment with house being built but I'm so tired coffee has stopped working on me. Please some one anyone tell me how to be nice about this because I'm too cranky to think. Thank ladies so much as I write this with an hour of sleep. :)
