you can always do both (provided bubs lets you). alot of women will simply do one or the other and i don't think there is anything wrong with either of those methods. but you could breastfeed some of the time and then express and allow your dh to feed some of the time too. that is what i did when jelly was newborn - it meant i could get some much needed sleep and dh could bond. (it only lasted a couple of weeks in my case though, because i started to find that simply breastfeeding all the time was a lot more conveinient - i didn't have to worry about bottles or expressing equpment or anything.)
