So when DD was about 6 months old and on Level 2 nipples I traded her bottles (Dr. Browns) in at BRU for the BPA Free bottles. I still had DD's Level 1 nipples from the originals so I put them on the returns and kept her new Level 2's. When I got the new bottles they had Level 1 nipples on them. I saved them in a ziplock bag (they were never used). Do you think they are still good or should I just pay the few dollars for new ones?

Re: s/o bottle nipples for new baby
Unless its many years afterwards, I would think they would be fine to use.
ETA which judging by your siggie won't be an issue
