You will find if baby cries and you put him on the breast, he will suckle... he is stimulating your milk production, even if he doesn't get much milk, it will settle him... and the more/longer he sucks is best for your body to get that "make milk" signal. so if he cries and you feel like formula will help, put him at the breast and see if that settles him.
As long as you give him pretty much unrestricted access to your boobs for the first few weeks, giving a little formula if he really isn't settling, wont hurt. what hurts is if you give formula but don't allow for him to suckle. because then you hurt your potential supply. also if you give him a little formula and find it puts him to sleep so he doesn't go on the breast, you could then pump.
My pump has a 2 min start cycle where it pumps quick little pumps, then it goes to longer slower pumps. this mimicks how a baby feeds, they start fast and furious to get the let down, then they can do long sucks and you will see/hear them start to swallow...
also - let down... mine was super powerful and quick.. and sometimes J would pop off sputtering because she got to much... thats ok, they learn how to control the volume of milk eventually. i found that laying down nursing - it was easier for her to deal with the let down, as she wasn't on her back and having the milk forced down her throat. and remember that if you can only pump a little bit and get worried, the baby is MUCH more efficient at getting milk out then the pump.
as for bottles - just make sure you have slow flow nipples. it is easier for a baby to suck milk through a nipple then out of your breast, so it causes the baby to learn he doesn't need to work as hard to feed, and then will refuse the breast because its too much work. so thats why they say no bottles for 6 weeks. i honestly think after 4 or so weeks the baby has it figured out and you should be ok, and i doubt all babies suffer from nipple confusion.
