I've seen a few posts in the last few days about used bottles, but most people say to buy new nipples. Sorry if this is ridiculously obvious, but why?
We got some from my SIL that my niece has used for the past year. They are in great condition and we washed the bottle, cap and nipple in the dishwasher and they look and smell fine. My niece was formula fed, but I plan to breastfeed and pump once I go back to work.
Re: Bottle nipples
Yep! All nipple and pacifiers should be checked periodically for breaks and tears and thrown away when found like that. We used stage 1 medela nipples until my girls were around 6 months old I think.
