Is it Possible for a Mother to have Her Career?

When I went home from work yesterday, my mother-in-law informed me that Dave fell down and knocked his head at the back. He cried extremely loud. This is the first time that he got knocked down very hard. Why did he fall down? Apparently his nanny made him sat alone on the floor. He fell down and knocked his head (at the back) on the ceramic. Ouch. She shouldn't do this as Dave is not that steady to sit by himself yet.

Then question arises. Is it possible for a mother to keep her job and to have her career? Or a mother just need to stay at home and look after her children? For me personally, I am not a home person. I can stay at home and look after my kid, but not for the whole time. I feel that when I still have the options, I still prefer to work. Nowadays, most of the mothers are working. Their children are still growing very well...
