Right now my sister, her husband, and their three kids (14f, 10m, 5m) are staying with me and my family temporarily while they are waiting on council housing. I have two kids (13f and 11m).
So I have four bedrooms in my house. The first is my own. The second one is my daughters bedroom. The third is my son's bedroom. The last bedroom is the guest room where my sister and her husband are sleeping.
From the first night they were here my son has wanted his 10 year old cousin to sleep in his room. Those two get along very well and enjoy each others company. So we set up my 14 year old niece and my 5 year old nephew in the lounge downstairs. My 5 year old nephew is apparently having a lot of anxiety problem so most of the time he sleeps in the guestroom with his parents.
My niece is unhappy with this arrangement because she feel likes she gets no privacy (downstairs is open plan). To solve this my sister wants me to force my daughter to share her bedroom with my niece. My daughter however is not as close with my niece as the boys are with each other. My daughter and niece have very different personalities. My niece can be loud and intimidating and my daughter on the other hand is very soft spoken. Having so many other people in the house has already been making her feel stressed and overwhelmed. All three boys being younger and energetic can make things feel chaotic. I don't want to force her to give up her only private area to retreat to for peace and quiet.
I told my sister that we can try to add a privacy curtain to a corner of the lounge for her daughter. My sister said that wouldn't help at all because anyone could just barge in. She says that a teenage girl should be able to have access to a lockable room especially in a house full of mostly boys. She doesn't see any issue with the girls sharing even though I told her my concerns. She thinks it would be a good opportunity for them to bond.
Another issue we've run into involved a weekly dinner I do with my kids. So far we've had no issues with regular dinner as we all contribute to the groceries and all the adults take turn cooking. I however would get my takeaway for my kids once a week. I let my them take turns each week to choose what they want. It's a treat at the end of the week that they both look forward too. My sister and her husband have a tight budget so they cannot afford to buy takeaway regularly. While I am a better off financially paying for everyone every week is not feasible as it is already expensive and it would cost double.
I thought that eating takeaway in front of them at home would be cruel though. I've had a little discussion about it with my kids and told them that while my sister and her family are staying with us we would be having our weekly dinner out instead of doing takeaway and eating at home. I thought this was a fair compromise.
My sister did not agree. She says it's obvious that we are going out to eat good food since we leave before dinner and when we come back home we don't eat anything. While my kids won't brag about going out to eat they will answer honestly when my niece or nephews ask where we went. They then end up feeling bad and my sister says they wouldn't feel bad if I just said no to my kids and that it wouldn't hurt my kids to not go out as often. I will also add that on a selfish note I don't want to stop taking them out to eat because its the only time I get to have with just the three of us alone now.
