Things have changed a lot nowadays. I am a proud mother of a single daughter. For me she is my world.
Now parents are accepting female kids. Such discrimination mostly seen in rural areas.
"Dowry" Dowry and only Dowry - It's the no:1 reason why many parents dont want girl kids. They also think that if they get baby boy, he will bring 'Lakshmi' to home. Our traditional values too have always given boys an upper hand.
But I feel that parents need to spend more money on boys than girls. Girls are almost limited in their desires, and they remain behind the shadows of their parents in most cases. So, a girl may be satisfied if given a degree or PG education and less expense on her daily routines. But male kids are not so. In most cases, they demand for better education, better pocket money etc... (Parents are not reluctant to spend on male kids comparing girls as they foresee investment return in terms of dowry).
NB: Things told above never follow 100% in all cases, just a few instances.
