I did think of that one too and the swimming one! So you're not nuts

I definatley felt the pop of my waters breaking. I was in the bath for Angus and sitting on a fitball for Caleb. Both times it was in the middle of a contraction and I could feel the relief of pressure for a sec or 3 while the fluids poured out, then with the next contraction it was like someone had cranked up the intensity.
