We've got 2 Girls and although we definitely weren't trying to gender sway, those theories state that we should have had 2 boys! I was charting while TTC and am therefore very aware of my cycles and when we conceived both girls. DH isn't sporty at all but he does drink a lot of caffeine, if that makes a difference

My sister has 2 boys (and she is from the same family as me so G,G,B) and her DH is from a G,B family. Both her and her DH are very sporty too (super active!) so they blow the sporty = Girls theory out of the water too.

Both DH and I are from G,G,B families and both our mums had a larger gap between their girls and boy babies. It will be interesting to see what we have when we try for #3 given the age gap will be bigger too.

I honestly believe it's just luck of the draw though and with only two possible outcomes (ie Boy or Girl) the odds are literally 50/50!

It's fun speculating though
