you havent had your baby yet right?
then i would really recommend trying to breastfeed when he/she arrives. if you get help from the midwife right from the start it will be fine. when i was in hospital i would ask the midwife to help latch baby on every time, otherwise you can get really sore, you have to ask though as they just leave you to it. also use Lansinoh Lanolin cream on your breasts before and after every feed.
Once you and baby have got the hang of it and you are producing the right amount of milk for baby then it is the best thing, i loved it and it is less hassle than making up bottles and its free.
If you try it you can always change to bottle feeding but you cant do it the other way round.
Good luck with everything esp giving up smoking x
