As AJP said keep an open mind about staying especially having your first child. However, I have done both and I prefered not staying in hospital.

In hospital you don't sleep,and you are exposed to nasty bugs etc. However I did stay in hospital with my first and I used the stay as useful resource for information and learning about breastfeeding etc. In saying that if you have a midwife coming to your home regularly then you may not need to stay in hospital at all. I certainly prefered coming home to my own bed, my own shower and a husband who doted on me for at least 24 hours.

Good luck with your birth and decision.
