Gosh - things I packed last time that were absolutely not necessary
Lip balm (because I read that the gas and air can be drying on your lips....jeese who cares about your lips when a baby is popping out your fangano)
A book (no way is there time to read a book, before your birth you will be in labour and not really in the reading frame of mind....after your birth you will be obsessed with your baby, and knackered)
Flannel (for my dh to mop my brow. He forgot)
Towel (it will get bloody, use the hospitals)
Things I sent my dh out to get when I was on the ward
Snacks (they give you toast post birth but that was it for 13 hrs)
Arnica (sp?) tablets to help with the bruising
IMO scratch mitts are a waste of time. When they are born their nails are so soft they can't scratch anything. By the time they harden the mitts just fall off. The suits with the mitts sown in are brilliant.
Bibs are also not necessary at this age if your planning on bf?
Similarly if you are planning to bf then nursing bras are the things to bring. The 'A' frame ones and the most modesty preserving ones.
Tena pants sound uncomfy? Big Bridget Jones pants with a high waist (in case of a section - you don't want the waist band rubbing the wound) and the biggest softest mattress type towels for the bleeding.
