One of the kinder things you can do for your sibling is offer to help them with their homework and their other school work. If they have an oral presentation coming up, offer to listen to their present them presentation. If they are struggling with their math assignment, sit down with them and help them work through the assignment. Focus on practical ways to help your sibling succeed by offering your knowledge of particular subject or simply a helping hand so a project gets done on time. You can also offer to help them complete their chores around the house or split them with them if they are working on a tight deadline for school. Maybe your sibling has a performance coming up or a big sporting event. Make an effort to be in the audience and cheer them on from the stands. Attending their special events will be a nice thing you can do for them as a way to show your support as their big brother or big sister. As the older brother or older sister, you should watch out for younger sibling and stand up for them if they get into any awkward or sticky situations. This may be confronting the school bully if they start to pick on your sibling or mediating a fight between your sibling and your parents. Try to stay on your sibling's side and work with them to resolve any problems or issues with others. Having your sibling's back will show them that you are willing to be there for them and support them. A good big brother or sister will act as their sibling's champion and encourage their sibling to be the best they can be. Take notice of your sibling's abilities and talents, and then actively work to help them develop and improve them.  For example, if your sibling shows an interest in painting, encourage them to take art classes or to set up a painting studio at home. Alternatively, if your sibling wants to go to an Ivy League school, help them achieve this goal by helping them with college applications and drafting a personal statement.
