I second reading The Womanly Art of Breastfeeding. My girls are only 17 months apart, but world apart in how they nursed at the beginning. I was very lucky with my 1st. She latched right away. Slept 3-4 hours until about 3 months and STTN (5-6 hrs). We had the initial 6 weeks of learning, but she was born to nurse!
My LO was much different. Nipple confusion, nursing every 1.5 hrs until nearly 8 months and then still nursed all night long. It was a completely different experience. One I didn't anticipate, either. I really thought she'd be just like her sister (boy was I wrong-she's nothing like her sister in anything) I think you have an advantage by asking all these questions! Just the knowlege of knowing it may be different is good. I'd also read up on a good latch, too. I hadn't realized the lazyiness in my toddlers latch until I was teavhing a newborn to do it properly!
