I wonder if this is permanent or if you have a big gap does it 'reset' back to being neutral?
Good point Onyx.

My mother would say it does, she had my sister and I 2 years apart and then later went on to have my brother 5 years after. She keeps telling me if I have a big age gap she would bet money that I have a girl. My age gaps are no bigger than 15mths so it would be curious to see if we go on to have another with a 4+yr age gap from the last boy what gender it would be.
