I have tommy tippee closer to nature bottles.
I'm pretty sure the instructions say you have to buy new teats every month (if it's not a month it's some other length of time).
Is this yet another of the rules about breastfeeding that everyone ignores (like the rule that bottles should be made up fresh nowadays, not made then stored in the fridge).
Or is it actually a really important rule, like the rule that powder has to be made up with water that's over 70 degrees?
thanks xx
