Newborn footed pajamas- they live in these the first few weeks, definitely get a few newborn sized clothes since people tend to get you 3+ month clothes. Kimono style clothes are also amazing those first few weeks since putting clothes over the baby's head can be super difficult!
Travel Crib- we got the Baby Bjorn and LOVE it. It's expensive but super light and small and so much easier to set up than the traditional guys. We didn't ever have it set up at home so we didn't miss the changing station but some folks do use it downstairs in the beginning when you're changing 10+ diapers a day. People also really love the Lotus travel crib.
Carriers- for when K was a baby we used the Baby Ktan which we loved but once she got bigger we transitioned to the Ergo 360 which we also love. Definitely go for the 360 over the regular ergo (if you go that route) because they can face out. I use ours pretty much every day.
Stroller- we went for the UppaBaby Vista which is expensive but amazing. I used the bassinet until she was almost 5 months old and we used it in her room as her sleeping quarters for the first two months (when we thought she was too small for the crib). UppaBaby also has the Cruz which is the same thing but doesn't convert to a double so if you're thinking one kid, that would be the more cost effective way to go. A lot of people also have the City Mini strollers which fold with one hand. I personally loved having the bassinet option but I think you can purchase one for the Citi Mini separately.
Umbrella Stroller- we got one of these guys (Maclaran Triumph) but barely use it, I think if we were in the burbs we would but since I mostly walk everywhere I use our big guy, I think it's probably good if you travel a lot.
Rain cover- make sure you get one for your carseat or bassinet, I used it nonstop in the winter.
Video Monitor- we have the Samsung which I really like, the other really popular one is the Motorola. I think the Samsung could have a better range...
Bundleme- also AMAZING for the winter so you don't have to put a coat on the baby.
Play mats- you need one of these and babies love them. We have the Skip Hop one and really like it.
Swings- we didn't go this route, instead, we have the Mamaroo which was a life saver for the first few months but she's now pretty much grown out of it...
Bouncy seat- these are light and you can carry them from room to room which is amazing. We have a Fisher Price one but a lot of people love the Baby Bjorn bouncers.
Bottles- we used the 5 oz Medela bottles and then also got the larger Born Free bottles that we started using when K was about 4 months old. You want both. You can also pump directly into the Medela bottles which is amazing.
Pacifiers- if you have a baby that likes these, they are lifesavers (and I don't believe in nipple confusion, I'm pretty sure my baby always knew what was my nipple... and it wasn't her pacifier). K really liked the Maam when she was an infant... make sure you get a thing that attaches the pacifier to the baby (I wish I had one of the guys that is also a teether).
Burp clothes- we love the Aden and Anais ones but I heard that cloth diaper inserts also work great.
Bibs- I actually never put K in bibs but now that we feed her solids we love the Baby Bjorn one because it catches all the extra food!
Sheets- you should register for 3 sets of sheets... Trust me.
Changing pad- you will need a changing pad and atleast 2 changing pad covers as well as the waterproof liners that go on top. You'll go through a lot of these at the beginning.
Glider/Rocker= lifesaver... best investment ever. Mine is from Pottery Barn and is a rocker that converts into a normal chair.
Jumperoos/exercauser- I would buy this used and not register for it. They're HUGE... plus you don't need it until the baby is 3/4 months old.
Car seat- we have the Chico Key Fit and love it. It's really popular and got great reviews on Baby Bargains.
Nursing pillow- I would definitely recommend a Boppy. I have one upstairs and downstairs.
Diaper bag- I have the Pottery Barn one which I like, the Skip Hop one is also really popular.
Swaddles/Sleepsacks- get the Halo ones, I liked the cotton ones that are also velcro swaddles, I think we had two and we could have had more. The velcro is amazing and makes swaddling SO much easier. You'll also want a couple of sleep sacks without the swaddle for when they get older.
Swaddle blankets- you definitely want a set of the Aden Anais ones. I got two sets and probably could have done with just one set.
Bottle Drying Rack- I really like our Skip Hop one because it doesn't take up a lot of space.
Humidifier- you will want one of these especially if you're in an old house.
Baby first aid kit- the Summer Infant Complete Nursery kit is great and even has teethers and a hair brush, definitely a good thing to have on hand.
Nipple cream- Boob-ease natural nipple balm is 100% organic and safe for the baby to consume. You'll definitely need some of this if you're nursing.
Nursing Pads- I originally got the disposable ones but you could see them through my shirts and bras and they weren't think enough for night time. I definitely recommend the reusable Bamboobies which are much more comfortable, easy to conceal and they even have the overnight ones that protect you all night.
Breast pump- you can get one of these through your insurance company which is amazing, The Medela Pump in Style or Freestyle are my favorites.
Milk storage bags- I would definitely recommend the Lansinoh bags because they lay flat.
Night light- another thing you'll definitely want. I thought I didn't need one but when you're in and out of the baby's room all night it's nice to be able to see where you are going :)
Baby bath tub- we have the blooming bath that we used in the sink when she was really little and now we use it in the tub for her to lay down on, we love it.
Crib mattress cover- you need this for when they pee through the sheets :)
Diaper pail- I love our Dekor Plus because it has a foot thing (and it's better looking than the traditional guy).
Sound machine- get the adult one, we got the kid one at first and it would turn off and wake her up so I ended up ordering an adult one off of Amazon that she loves. Bonus points that it has an ocean sound which means she's a great beach sleeper :)
Bumbo we love this now and actually use it to feed her as well as have her sit in while I (gasp) make dinner. She also loves the tray.
Wipes dispenser- I really like having one even though it isn't necessary....
Baby towels- register for a couple of these and washcloths.
Stroller blanket- you'll get tons of blankets but you might want to register for one you like.
Crib skirt- you'll need one of these guys, a bumper is up to you, there's some controversy on it
Nursing bras- you definitely want a sleep bra that you can wear all the time and you'll also want a hands free pumping bra. I'd also recommend a nursing tank top so you can bring it to the hospital.
For all you veterans, am I missing anything?!
