I remember sleeping with a black bin liner under my bed first time - very sweaty:)
My waters actually broke whilst gently bouncing on my birth ball eating my breakfast.
I think its quite rare for your waters to go in bed or asleep, guess gravity and pressure plays a role in it.
6 weeks to go and all I think about it baby, what position he/she is in, are they ok, will they turn from breech, will i get the labour i want? I play the whole scenario out from the first contraction to holding my baby. Its driving me mad, daydreaming all day, before i fall asleep at night, when i wake in the night - i am an obsessed woman, is this normal???
i keep trying to stop wishing my life away, may is half way through the year, march is not over yet but 6 weeks seems so close AHHHHHHHHHHHHHH!
