you'll probably find that the hospital has the facilities to help you immensely with this.

My DD was in special care for 24 hours and couldnt be breastfed for breathing issues so i had to express the colostrum (with a syringe to catch it...there is not alot!). and then they provided a electric pump (it is best to ask about their hiring policy of one of these from your hospital) once the milk came in. it can be tough going at first as it is harder to get your milk to come in manually, but can be done.

I would highly recommend contacting a lactation consultant (like the Aus breastfeeding association) as they have some great tips on how to get things going. and i think they also do more long term hire of the pumps...

HTH.
