We bought a few items we needed and did not need the whole bundled kit because as a whole, those kit items are kind of inferior. So when you consider everything, we probably spent more than the cost of one of those kits, but we ended up with quality products.
Here's what we got by:
soft bristled hair brush
bulb aspirator from the hospital and we bought the Frida nose sucker
small nail clippers
Vicks rectal thermometer (fast, safe and easy to use)
don't bother with those medicine droppers because all infant meds come with dispensers
