Maybe a left hander?

Well over the past 2 days Layla won't stop sucking her hands. Well Grandaddy came over and while holding her noticed this. He asked me if it is always her left hand. Well yeah it is!! So it is sometimes her right hand but mostly her left. Jatovi nor I had thought about this but does that mean she may be a lefty! Again who knows but if she is today was the first day we thought about it. As far as I know they only lefty's are Mycal and Myla. Only time will tell.
