C

    China has ended its long﹣lasted one﹣child policy，all Chinese couples now are allowed to have two children，which means that many Chinese children，including you，may have siblings （兄弟姐妹） in the future．

    Like many only children in China，Pan is happy and confident，except when she feels lonely every now and then．"It's not fun，especially when I travel with my parents．How I wish I could have a brother or a sister，"she said．Now it could be time for Pan to realize her dream．But what would it be like growing up with a sibling？

    Having a sibling can prevent children from bad feelings such as loneliness and fear，according to Laura Walker from Brigham Young University，US．"Siblings give kids something that parents can't，"she said．

    You may not feel lonely because there is someone else to play with．You can also talk about various things and share secrets with each other．

    But children with siblings also have to control their feelings and learn to compromise，said Laura．You need to share things with your siblings，including attention from parents，toys，the bathroom and even the TV．There is also unpleasant competition which you have to deal with．

    It's also said that the birth order decides how parents treat their children．Parents are usually very nervous and strict with their first child．So firstborns （including only children） have more sense of responsibility because parents set high goals for them．When the couple has a second child，they are more relaxed，less strict and have fewer rules．So late﹣born kids are usually funny and creative．
