Baby products- what you need and don't need

I recently found out that a friend is expecting her first baby. It got me thinking about what items I couldn't have done without for the first few months and which I could live without...

NEED

• Gilligan and O'Malley Nursing Tanktops- I have three of these, in pink, black, and white and basically rotated between them 24 x7  for the first three months of our baby's life. They are comfortable and convenient.
• Boppy or other nursing pillow
• Swaddles with Velcro- We swaddled the lower half of our baby's body, always leaving her arms out, most of the time for the first few weeks. After that we swaddled for sleep only for about another month.
• Breast pump- I love my Lansinoh but I know many who swear by Medela.
• Mam brand pacifiers- they look cute and are the right shape
• The First Years Breastflow bottles- the only ones we have used, are supposed to be more like breastfeeding.
• Kimono style onesies- Babies, especially newborns, don't like having things put over their heads and generally don't like being dressed and undressed. Our friends gave us a pack of these in newborn size and they were our go-to outfits for the first few weeks.
• Diaper Champ- Can be used with disposable or cloth diapers. You can use regular plastic bags with them so you don't have to buy expensive refills.

DON'T NEED

• Wipe warmer or bottle warmer
• Baby lotion, baby oil, baby powder
• Crib bumpers and thick blankets
• Bumbo

Also, as I have mentioned in several past posts, we are using cloth diapers (BumGenius brand) which are awesome! I would call them a "need" too.

Any items that you want to add/delete from these lists?
