I agree with the incontinence pads, i used them after having both my girls because they are bigger and feel nicer and i also think it is worth taking something to read or anything to entertain yourself (even if you dont use it) only because when i was having my second baby we had to go to hospital as soon as my waters broke (due to complications id had with DD1) and for the 3 hours before my contractions started DF and I were sooooo bored. No tv or anything and we could only walk around the hospital for so long. It was only lucky that someone has left a magazine in the room so we had the mega cross word to work on to try and pass the time before DD2 made an enterance.
And its nice to have something to do when all the vistiors have gone home, bubs asleep and you dont feel like sleeping (i had DF bring me more magz everyday i was in there)
