Do I still buy a couple of bottles, teats, steriliser just incase i need it one day? As in, would I need to start expressing and needing a bottle for this?
...DONT !. IF you plan on breastfeeding, dont have that mentality of 'just incase'....coz once you come across one hiccup during breastfeeding, esp in the first few days, believe me, you will resort to that 'just incase bottle' you bought.

Great advice by other ladies, no need to repeat myself.

If you intend to be with baby for its first few weeks of life....then IMO i dont think you need a sterilizer, bottle etc. Your boobs will do just fine.
