Do I need new bottles for DC2?

[Daffodilly]

Just getting myself organised for arrival of DC2. I'm hoping to BF again (and really hoping it starts better than with DD), but want to have bottles on stand by. I have half a dozen that I used with DD after she weaned. Any reason I can't re-use these? I guess I would just need new teats?

If they havent any scratches or cracks then they should be ok to use. I would definitely get new teats for them though.
