Hiya, am a first time mum with a 6 week old and after breastfeeding didn't work out for us we started on formula. I was bought a perfect prep machine and after talking to the HV today she told me they don't recommend them. Am now in a mess over what to do, am suffering from PNA and this has sent me over the edge. The machine has helped me so much am not sure I can manage without it. Am I putting my son at risk by using it? Any advice would be fantastic
