Miffster - after last week, I'd see it as an emergency bag, no matter what your birth plan is. You may need to go in for assessment at some stage and be kept in overnight and it's not nice being without everything.
I'd only pack enough for 24 hours (not including labour!) in any case as your DH or someone can always bring more in and if you're in and out quickly, it'll be annoying to be lugging around a bag with loads of stuff.
I didn't see breast pads on your list??? Or lip balm.
I'm packing...
Me (emergency/labour bag)
Breast pads x4
Maternity pads x2
Wash bag with mini shower gel/ shampoo/ conditioner/ moisturiser/ body butter/ toothpaste/ spritzing face spray plus lip balm (it's very dry in hospital IME plus panting dries your lips out!), facial wipes, deodorant, toothbrush, hairbrush, hairband
