Has anyone noticed paint coming off the bottles with light/green writing (bottles with dark/blue writing seem ok)? We only handwash and use sterilising solution and within 2 months all markings have disappeared, with paint ending up on the teat and other parts of the bottle! I have emailed Dr Browns several times, in the UK and the US, and had no response at all. Am getting angry as my baby has probably ingested paint and I am not even getting the courtesy of a reply!
