I bought little miss some clothes today
Do you have anything Bush or are you having to buy everything again?
Some of my suggestions are going to depend on whether or not you are breastfreeding, bottle feeding, combi feeding, or breastfeeding and pumping to feed baby with a bottle of breastmilk, if you are planning on making your own baby food, or if you are cloth diapering or using disposables (haha yeah, it gets a bit complex)
With some kids already, I would suggest babywearing, that way you can attend to your other children, and keep baby close next to you and happy. In those early days they really don't like to be put down.
So babywearing products, I would suggest a ring sling, Mei Tai, Ergo, Tula, or Woven wrap. Ergo and Tula have buckles so it's easy to use, ring sling is basically you put the baby inside, and then pull tight. The rest have long pieces of fabric to work with, so you will have to learn to tie them (youtube videos
) I have a ring sling and a Mei Tai already, I want to get a woven wrap this time around. I love having multiple ways to carry baby, I can switch back and forth whenever I feel like, plus some are just easier to use when baby is little versus when they are bigger or toddlers.
A pack and play, I would suggest one like this https://www.amazon.com/Graco-Playar...&qid=1438993781&sr=1-4&keywords=pack+and+play
it has a changing station and a sleep area, so you can keep everything on hand right near you, and the changing part comes out for when baby gets bigger.
Invest in some good burp clothes so you don't have to worry (as much) about getting thrown up on
A MamaRoo swing https://www.amazon.com/4Moms-Rockar...&qid=1438994410&sr=1-2&keywords=mamaroo+swing
They bounce and swing like mom does, and comes with white noise too
Swaddlemes, I love these things! https://www.amazon.com/Summer-Infan...UTF8&qid=1438994464&sr=1-2&keywords=swaddleme
They are just like swaddling blankets, except they don't come undone. You put baby inside, put the arms down, and use the velcro across the chest to wrap them nice and tight. Plus they are safe, never had to worry about a blanket going over their faces.
Sophie the Giraffe teether, the best teether ever https://www.amazon.com/Vulli-Sophie...00&sr=1-1&keywords=sophie+the+giraffe+teether
but beware, she squeaks like a dog toy
Gumdrop pacifiers https://www.amazon.com/First-Years-...d=1438994719&sr=1-1&keywords=gumdrop+pacifier
These are a personal favorite of mine.
A pacifier clip to keep the pacifier from getting lost, or falling to the ground and getting dirty
pacifier wipes for when you don't have time to wash them
Other than that I buy a lot of natural, lotion, bath, and diaper cream products
she was fairly calm and relaxed in there, even when the tech had me move about, stretch, and roll onto my stomach on either side, she still didn't put up much of a fuss. He had guessed she had grown used to hearing 2 older siblings around me and having them jump about around me that she wasn't bothered by much 
I'm sorry hun. That lady was rude and the way she acted was uncalled for- especially after you told her you'd already had your DD checked out my the Dr.
