dear sir. my wife just asked a question and shame on me. i cant answer. help me. my youngest daughter is now 5 yrs.old. she is the only left hand writer in the family. my family and my wife. no one is left hand user. how is this possible? is that because of the blood transfusion that my wife took when she was about to deliver her? my wife also query. my daughter is the most talkative, most shy type too when it comes to dressing where she hide herself to change. not like her elder sister who is nine who is not that shy when it comes to dressing in front of us. My wife group is AB and she receive blood transfusion few days before LSCS. because her blood was low.
