Onsies- 8-12 in 0-3 month size
Knit footie pants- 4-8 pair
Socks- Go ahead, get a couple pairs, but they will be lost before you know it! Perhaps baby will get to wear them!
For Cloth diapers I don't recommend spending money on the newborn sizes. Get all in ones or prefolds in the small or medium sizes.
For disposable diapers, don't stock up too much on the newborn sizes as the quickly grow out of this size! (in a matter of weeks)
Cloth Wipes - 24-36 wipes will be a good amount to have and will last for the life your diapering stage.
Disposable wipes, get the non-scented ones, Target brand Up and Ups for sensitive skin are the most economical and most gentle I have found.
This is where things get crazy, everyone loves to give baby blankets but you will have possibly 2 that you use. I recommend a gauzy cotton swaddle blanket set like the Aden and Anais brand as they are super versatile, lightweight and breathable. These are used for so many things, swaddles, shade, warmth, nursing cover, toy etc... Then get a couple heavier quilts or fleece blankets.
Moby wraps are excellent for the infant stage, then graduate up to a soft structured carrier like an Ergo or Boba. So many to choose from. Borrow them or if you are my client, I have a library for you to try out!
I loved my bouncy seat, I used it all over the house. Get a simple lightweight model, the type that will allow you to remove the overhead toys. I used it to put baby in after bath, while I showered alone, I moved it all over the house where I wanted him nearby and in a safe supported place.
Nail Clippers -I don't like the baby nail clippers that come in the gift kits. NIGHTMARE! I like a slanted nail clipper or hangnail nippers as it lets me see what the heck I am doing!
Cool Mist Humidifier
Nose Suction - Use the bulb the hospital sent home with you or a Nose Frieda.
A good breast pump is essential if you are nursing. Check your insurance plan as many are offering a free pump with your plan which is amazing! You can rent hospital grade pumps, buy a used pump as a long as it is a "closed system" pump. Or register for one and have family/friends go in for one. Definitely get a double pump to shorten the time you are at the pump. I also personally liked having a single manual pump if I was on the go. If you work with a Lactation Consultant they can show you how to properly manually express your breast milk and you won't need it!
Even if you are breastfeeding you may want to give your little one a bottle while you are away. There are a lot of bottle brands to choose from and Dr. Browns bottles get a lot of good feedback as it does not allow baby to suck air in while feeding, thus eliminating excess gas and spit up issues. As a new mom, the straws and parts of the bottle felt a little to fiddly for me to clean so I went old school. Slow flow nipples and the Playtex Drop Ins were what I used along with the breast milk storage kit. I also used a few of the glass bottles too and he did okay. It will come down to a preference for you and your baby.
High Chair- Space saver high chair. Nothing more to say.
Infant Car Seat - Tons to choose from. Pick your favorite. I like the Baby Bargains site.
You have a few choices, Crib, Portable Play yard with Bassinet, Co-Sleeping. I guarantee you will do at least two of these!
That's all folks. What did you use that you found essential?
