I've skimmed most of the replies and ti seems that you've gotten some fantastic advice.

The only bit that I would stress is the "don't buy formula" bit. Unless its a medical emergency (and if you're told it is, I would seek a second opinion to be sure), giving a young baby formula can do way more harm than good. Even one formula feed can strip the baby's gut of the protective bacteria and other nutirients that BM provides. So don't do it unless you HAVE to.

Good luck.
