In these days an increasing number of people chose to have children later during their life. I think it happens because now women, who are more responsible for giving birth, have more opportunities within their career and personal life than in the previous centuries, so they decide to build success life first. I believe that it is a very good tendency, established adults can offer more to their children.
To begin with, having children is quite responsibly and difficult, after all you should provide them food, safety and education. Parents have to have opportunities to give them all of it and it is impossible without a good job. It is clear that you can not get high salary job whenever you want, so adults should make an effort and spend a lot of time to become employed. In most cases these process can take up to 10-15 years but it worth it and the majority understand that. So, they spend their time on that first and then decide to have children.
I am sure that advantages of this trend outweigh the disadvantages, because all children deserve the best things during their life: high quality food, good education and perfect insurance. Parents with money, thanks to their job, can give them all of it. I know that a lot of people are afraid of some health problems, which can be caused by late childbirth but in our days medicine is very developed and this process can take place easily for both women in early 20s and 35 years old and plus. Also, now there are a lot of ways how you can have a baby instead of doing it by yourself, for example, adoption or surrogacy. It is not a problem right now.
In conclusion, I really like that a lot of people decide to have children later. I think that is how we can provide children a better life.
