I have some bottles that are 4 and a half, almost 5 years old. I used them for only 2.5 months. Should I just buy some new nipples for a newborn? Or buy new bottles and nipples?
Depends on the bottles condition, but you should be ok sterilizing and reusing them, but would definitely replace the nipples and any other soft parts.
My sister gave me her set of bottles when DS was born two years ago. I had to buy new nipples and then I sterilized everything together. They worked great.
I just used our 5 yr old bottles for DS2. I sterilized the bottles and bought new nipples and valves (born free brand). Worked perfectly and still using them now with the sippy spout.
Re: Reuse old bottle and nipples?
i kept all of DS's old bottles for potential future babies but i threw away all the nipples.
