My sister got married three years ago, and now her son is one year old. Last week, my sister was very busy, so she asked me to take care of her children for half a day. I agreed without hesitation, because I thought it was a very simple thing. But it turned out to be wrong. My nephew is always moving. He is too young to walk, so he crawls everywhere. I need to pay more attention. Because once he leaves my sight, something bad will happen. Although I sit on the chair, I can't do anything. I'm very tired. When my sister came back, I was relieved that it was not easy to raise a children.

三年前我姐姐结婚了，现在她的儿子一岁了。上周，我姐姐很忙，所以她叫我帮她照顾孩子半天。我毫不犹豫地答应了，因为我觉得这是很简单的事，但后来事实证明是错误的。我侄子一直在动，他太小还不会路，所以他到处爬，我需要集中注意力，因为一旦他离开我的视线，总有不好的事情发生。虽然我坐在椅子上，但是我什么也做不了，很累。我姐姐回来的时候，我总算松了一口气，养育孩子真不容易。
