CurrantBun, if you want to breastfeed I would avoid using formula feed at all if you can, as it will restrict your supply. Breastfeeding is programmed to produce as much as the baby needs, but it's easier if the baby is feeding a lot as the breasts get more stimulation/messages to make more milk that way. Hope that makes sense!
On the other hand, if you want to have the option to use bottles as well as breast, make sure the baby is used to both within the first 6 weeks otherwise it will probably refuse whatever it isn't used to. I used a bottle of expressed breast milk every evening last time round - did this from week 5 so my baby would always take either breast or bottle. Very useful when I wanted a night out with the girls 2 months down the line!
Breast pumps - so many different women have different experiences about this. I used an Avent Isis manual pump and it was fine, but some women find they can only use electric pumps, and others can't express at all.
The Lansinoh cream is the best, but you have to use it with breast pads! It is very greasy and yucky, so you'll get that nasty yellow goo all over your clothes if you don't protect them with pads. And only use a tiny amount, like very expensive face cream. I used it after each feed last time, and never had any problems with mastitis or cracking, but I can't see the point of using it before the birth.
Sorry for long and bossy post, but reading yours brought back all the breastfeeding stuff!
