Is It the Old Generation's Duty to Look After Kids 老一辈有义务去照顾小孩子吗

Many years ago, in order to control the fast growing population, the government carried out the policy of Family Plan, which indeed helped to control the population and make Chinese economy develop fast. Now, the second child policy has been advocated. It is the good news for those families who want to raise one more child. But the problem comes. Many young people need to go to work and they don't have much time to take care of the new born babies, so they ask their parents to look after their babies. As a result, it seems to be the old generation's duty to look after the little kids. According to the report, a retired woman became depressed after taking care of her daughter's second child. Actually, the young people should not rely on their parents too much. Everyone has their personal space. 
许多年前，为了控制快速增长的人口，政府实施了计划生育的政策，这的确有助于控制人口，使中国经济快速发展。现在，随着二胎政策的提倡，对于那些想要再抚养一个孩子的家庭来说是好消息。但问题来了，很多年轻人要去工作，他们就没有多少时间去照顾新出生的婴儿，所以他们叫父母帮忙照看孩子。因此，似乎变成是老一代人的责任去照顾小孩子。据报道，一位退休的大妈在照顾她女儿的第二个孩子后患上了抑郁症。实际上，年轻人不应该过于依赖他们的父母，每个人都有自己的私人空间。
