I used some of the stuff people didn't!
Used a baby bath and change table often. Used mittens, as DD would attack her face with her nails when she was tired as a newborn. It meant she remained a cute little baby, not some scratched-up scarred freak (well, that's a bit extreme, but you know what I mean... lol). Also loved my breastpump when my milk came in. I had decided not to buy one... until that lovely engorged, painful moment when I filled up with milk. It was amazing then.
What I didn't use though? The expensive nappy-wrapper bin. Cartidges are overpriced, and it was a PITA that didn't really do much to hide smells anyway. No point. Took the top off and just used it as a regular bin... lol. Could ahve saved a lot of money if I'd just purchased a regular bin instead.
Also the million baby oils and baby powders people gave me. Total waste of money - I don't know why anyone gives you these things.
