Even if you don’t like to run or play video games, try to do something your brother or sister enjoys. They’ll appreciate that you showed an interest and, even more importantly, will enjoy spending time with you. Take the opportunity to ask them more about the activity they enjoy. This will allow them to open up and can get the conversation going. Regardless of how old (or young) you are, games are a great way to bond with your sibling. Try to learn a new game together or pick one from your childhood that brings back memories.  Don’t choose a game that has a history of causing arguments. If, for example, you can’t get through a game of Scrabble without name calling and arguments, be sure to pick another game. Playing a basketball game outside or a good, old-fashioned game of miniature golf counts too! Relive happy moments together by looking at family photo albums. You’ll enjoy looking back at some of life’s best moments and will hopefully remember all of the good times with your sibling. Whether it's a weekend trip or a movie marathon, establish a tradition with your brother or sister.  You can do it on a monthly or yearly basis. For something like a trip, it may make sense to do it yearly. Movie marathon's though, can be done on a monthly basis. Try alternating who picks the movies and snacks as part of the tradition!

Summary:
Do their favorite activities. Have a game night. Look at family photo albums together. Establish a sibling tradition.
