Leftie or Rightie?

Mummy observes that I use my right hand more than my left to grab toys. Does that mean I am a right-hander? But experts from BabyCenter says otherwise. At 7+ months, it is still too early to tell. Probably have to wait a few more months or up to my 1st year birthday. When Mummy gives me a toy to hold on my left hand, I will grab it, too. But just that I use my right hand more often.

Does it matter if I am a right- or left-hander? Daddy told me that Grandma used to scold his sister when she was young for using left hand to write. It was seen as not normal because most people use their right hand. But my Daddy's sister (my auntie), secretly practised writing with her left hand anyway. And she grew up to be capable of using both hands to write. She is also the smartest child in Daddy's family. Hmm... something to think about.
