When searching for a Dr Browns steriliser on the internet I came across all this information on BPA in babys bottles (Bisphenol A a material in plastic) and some American sites mentioned it being in formula tins. I have been so worried since I phoned dr Browns and they said it is in their bottles but at a safe level and nothing would be on the shelves that was not safe and Aptamil assured me that also no issue with formula. I have found botles made by MAM that are BPA free however they are quite cheap which also makes me worry!!! Should I change to BPA free bottles dd is 14 weeks old and I stopped breast feeding 2 weeks ago used dr browns hoping the transition would be easier - going well - would be grateful to hear if anyone else worried or for someone to tell me I am worrying unnecessarily.
