Okay, FTM here, and I'm a little bit confused about everything that I'll need to breastfeed. I'm finishing up our registry in the next couple of days and this is what I have so far. (This isn't all going on the registry, some stuff I'll just buy, I just want it all figured out this week, ideally.)
-breast pump (insurance covered)
-breast feeding pillow (I chose my breast friend, unless there's any reason I shouldn't!)
-nipple shields (2 - do I need more?)
-lanolin
Then, beyond that, what do I need? I'll be pumping as well as breastfeeding directly, so I assume I'll need bottles and a bottle warmer and some other things. I've seen some sets that have milk storage pouches/racks, bottle warmers, bottles, etc. Are there any sets people recommend or is it better to just buy the items individually? If individually, are there some things in the kits I won't need or is it all necessary?
For reference, kit wise, has anyone used this starter kit set? Does it all look good/necessary? If I bought it, would I be all set, once I have the other items I mentioned at the top (pump, pillow, nipple shields and lanolin)?
If there's anything I've overlooked, please let me know! I am kind of overwhelmed with the breastfeeding aspect at the moment. THANK YOU! 
Re: Let's talk breastfeeding accessories - what's necessary? What brands do you like?
Lanolin which I only used a few times.
Nipple shields, I only needed because ds oral muscles weren't well developed at first and we phased those out. You may not need them.
Breast pads until milk production regulated.
Lansinoh milk storage bags- froze milk in increments of 4 or 6 oz. Lay them flat on a cookie sheet until frozen then stored them in plastic shoe boxed that were labeled with the dates of the milk inside.
Never used a milk warmer, just microwaved a big mug of water to warm the bottle in.
Between pumping I put the parts in a gallon zip lock bag in the fridge and washed them at the end of the day.
-Medela breast pump. It was nice to have the Medela because the hospital gave me a ton of Medela pump parts that were all interchangeable with my pump.
-Boppy. I know some people like the Breast Friend, but I'm somewhat of a minimalist and liked that the Boppy could be used beyond breastfeeding for things like helping baby sit supported.
-Nipple shields. I ended up needing several of these be said DS took a while to latch correctly, but you may not need them at all, so two should be fine. The hospital also gave me some.
-Born Free bottles. I swear by these as we tried several and they were the only ones DS would take. This time around I'm going to get their glass ones because breast milk is somewhat oily and after so long I felt like I couldn't get any of our plastic bottles clean clean, no matter how much I washed and scrubbed. Glass is also easier to heat up in hot water. (We didn't use a bottle warmer)
-Breast pads. In the beginning you leak A LOT, so the disposable ones are nice. Once things settled down I switched to the washable cloth ones.
I used a boppy, not sure how it compares to other pillows. I liked it because I could use it to prop up baby for tummy time, looking around, etc.
You'll need milk storage bags if you plan on keeping a stash, assuming your milk doesn't need to be stored in glass bottles, freezes ok, etc.
you may also want breast pads so you don't soak yourself when you have a let down during the day.
I preferred the reusable breast pads called bamboobies.
Loved loved loved My Bestfriend Pillow.
I'm planning on making some lactation cookie dough to freeze before I deliver so I can just thaw and bake as needed. Here's a recipe I found that I'm planning on trying: https://www.bellybelly.com.au/breastfeeding/lactation-cookies/
No breast shields unless you already have a reason to know you'll need them.
Really, for breastfeeding you just need a comfy spot and your boobs, and everything else depends on your lifestyle and needs. I am a SAHM but am fairly social and spent a good amount of time out of the house so I pumped regularly and used a cover and storage bags etc. Have fun shopping!
