i'm exactly the same! I remember years ago before dh and i were old married s with kids we were watching a programme were someone gave birth and i was in floods, saying " its so beautiful" etc. I think he was vvv scared!!!
I'm so sad whenever I go round to my mums I put sky on and go straight for discovery health. Then I sit and watch intently despite having seen every programme at least 5 times already. And then I sob uncontrollably when they give birth. Very worrying considering when I was first pg I was sick after watching a baby be born by cs on "9 magical months"!!!
