I need help, please! Thanks It quite difficullt to know 100% i fis better to have a small age difference betwen siblings or a large one. I would say that the sibligs relationship depens more on your personality than the age. From my personal experience, the competition and the rivalry are less when the age difference is larger. The things that you want to do or you want to have depend on your age, so the most age difference you have the less possibilities to want the same thing you have therefore less competition between siblings. However, with respet to the friendship maybe will be better if the age difference is small because it will be easier to have similar tastes and preferences, so you will be able to share more memories. In your live you are learning from your owns mistakes, that’s why I think that definitely if have a large age gap you can benefit you to learn about your siblings life and share your own experiences. In conclusion, I prefer to have a large age difference.
