For your actual birth use an old nighty or if buying new buy the cheapest as the chances are you wont be using this again.My husband used his head and picked up some of my favourite relaxing cds & bubble bath(I had many baths whilst in labour on my first as the warm water was really soothing),.Check to see if your hospital has a birthing ball as this enabled me to get into a really comfy position,also some energy sweets, chocolate or bananas to give you energy throughout the birth.Dont forget a camera/videocamera.For after the birth take enough baby essentials .eg. lots of nappies, wipes, babygrows,vests & a going home outfit.For mum lots of cheap knickers or diposable ones(a must),nighties & day wear, comfy leggings & t shirts if staying in,magazines, shower essentials & any medication or creams that you may need, it is sometimes advisable for the birthing partner to take a change of clothes and refreshments, take some cash incase there are no cashpoints near.You should be given a bounty pack, which includes samples for mother & baby that come in usefull.
