Do you think your parents love me more then your sisters or brothers?

I have two sisters and a brother, and I keep good relationship with all of them. Certainly, when I was a young kid, my parents tended to spoil me and gave me more care; but after I had grown up, my parents share equal love between the four kids. I think it's not a good way of bringing up children by spoiling one but neglecting the other. This will affect greatly the relationship between brothers and sisters. I think, what my parents have done so far is right.
