Old bottles or new?

[NikkiTwinkle]

Hi
New to this so no shorthand sorry. I'm expecting baby no 2 in 5 weeks and have saved my old bottles from baby no 1, now 4.5 years old. I'm buying new teets, but do I need to buy new bottles?
What is the difference as I hear the new ones are PPE free (Whatever that means).
Any help would be great.
Thanks
Nikki

The PPE free thing is because some bottles/plastics when heated have been found to release chemicals (not a nice thought in your baby's milk). Suggest you google if you want more info about this.

If you do want to use the old ones I would just get rid of any if they look scratched/worn as they will probably harbour more bacteria and be more difficult to really clean.

Good Luck!
