HI,
Congratulaions on your pregnancy. It is normal to be a bit aprehensive about the early days. I have to agree with Manta - the best preparation goes on in your mind.
The first feed is very important. Babies don't know what nipples "should" be like - they love the ones they are given. If your baby is born normally, without drugs, that will give him or a her a great start. It is important that babies be kept skin to skin with the mum, and be allowed to feed early. They are very alert and aware in this period - primed to feed. And they will tend to "imprint" a way of feeding (that's why it's important we don't give newborns bottles)
You may find it really useful to do an ABA class, and borrow Sue Cox's dvd "Mom and Baby I can do that".
It sounds like, despite the early setbacks you did a great job with your first baby. Good on you! I'm sure that with this one you will do fine
Regards
Barb
