Last week, my elder sister gave birth to a baby girl. I was so happy for our family joining one more member. I helped my sister to look after the baby. She was so small but looked old, and I laughed. This girl cried now and then. I had no idea what to do. When she peed, I had to change her clothes. Raising a baby is not easy. My mother has two daughters. It must be really hard for her, especially me, I was so naughty when I was one year old. Being a mother is a big decision, asit means to sacrifice a lot. I am so thankful to my mother. She is a good mother.上周，我姐姐生了一个女儿，我很高兴我们家有了新成员。我帮着姐姐一起照顾小女孩。她很小个，但是看起来却有点点显老，为此，我笑了。小孩时不时的哭，我都不知道要怎么办。她尿裤子了我就得给她换衣服。养育一个孩子真是太不容易了。我妈妈有两个女儿，她肯定很辛苦，尤其是我，我一岁的时候是很淘气的。成为母亲真的是一个重大的决定，这意味着要牺牲很多。我很感谢我的母亲，她是一位好妈妈。
