I have heard some killer stories about women competing in large poker tours while being in their eight month and stuff. But come to think of it, maybe it is a good way to get rid of stress and anxiety. I think in general that people fuzz too much over pregnant women. Don't they know very well themselves what suits them and what doesn't?
I think that it is really cool when pregnant women keep living their ordinary life, as long as it doesn't affect the baby of course! And who knows - maybe the baby will have great odds to come out as a great poker player?
