Mom of three here. My darlings range from 19 years to 7 months.
I have breastfed all of my children until they were at least 18 months old, and I would really encourage you to read "The Nursing Mother's Companion" which should be a free read from your local library. In addition, I recommend attending a couple La Leche League meetings before the baby is born. Nursing is wonderful and natural, but it is also a skill you and the baby both have to master.
With my third, the baby had been in the NICU, and given pacifiers and bottles, (against my expressed directions and without medical need) and the little one was really confused about how to nurse. I was an experienced nursing mom, but I needed help. I called my local leader who came to my house and really helped me get the baby "back on track" to a successful nursing experience.
Since I already had a relationship with the leader, it was easy to invite her to the house, but if she had been a stranger, I would have been much more reluctant.
As to baby gear, I suggest a sling, the Maya Wrap to be specific. It has been a wonderful tool from birth. It adjusts quickly to allow my hubby or older kids to carry the baby, it is wonderful for breastfeeding, and it is so much more comfortable than the Baby Bjorn type pack or "slings" sold at places like Wal-Mart or Target. The web site
www.mayawrap.com has a section of outlet offerings which are less expensive.
The Maya Wrap comes with an instuctional DVD. It really helped to be able to see directions in live motion.
The wrap has a small pocket sewn into the tail and I leave a diaper and a ziplock of baggies in there. When I am jumping out to run errands or quick jaunts. I just leave the wrap on while in the car and when I pull her out of the car seat I slip her into the sling and off we go. No stroller, no diaper bag. It is so comfortable and convenient.
With my older kids, I had a crib that was expensive but "turned into a bed when they were done with it as a crib." In my opinon, it wasn't the best investment. The long side of the crib did become a headboard, but I still needed to purchase side rails which were quite expensive. The bed that resulted was a full sized bed. It was just too big for their needs. I ended up selling the crib and buying a twin.
This time around we purchased, off of Craigslist, a Graco Pack and Play with the bassinet feature and baby changing station built into the portable crib. It was wonderful. It fit next to the bed which allowed the baby to be close during those early days and frequent waking. The changing station was handy for all those changes (10-12) a day the first few weeks, and now that she is older, she sleeps in her "little crib."
Not only did this cover three real needs in one item, but when we travel we can take her actual regular bed with us...which is a lifesaver. She is familiar with her crib, and she sleeps without any fuss or muss.
When she is able to crawl out, or hits 30 pounds we will switch her to a twin sized bed. This option isn't as pretty as the traditional wooden crib, but it was much more practical from our perspective. All of the experts warn against the crib bumpers and soft fluffy comforters that are sold for the standard cribs, but a traditional crib has such hard sides, people get the bumpers to soften any little one pushing up against them.
With the Pack and Play, the sides are a taught mesh, so they aren't a bumping or a suffocation hazard. We got some lovely soft sheets and matress covers at Target.
