So far in my labour bag I'm going to have:

snacks (nuts, muesli bars), energy drinks, heat pack, stress balls (suggested in a Birthskills book I'm reading at the moment), ipod, visualisation picture, bathers, aromatherapy oil and electric burner...also DH's bathers...

Haven't packed it as yet...as still waiting on my Ob's decision about VD or c/s....but hopefully I'll need it!!!
