My LO was poorly and holding her head which the doctors found really strange, she was sent to the hospital and luckily got better overnight after being ill for two weeks. They sent off a urine sample and it has come back that it had e-coli so we have to repeat. Why might this have happened? I’m really concerned.. her bottles are scrubbed and sterilised, the only thing I can think is we use a perfect prep machine - but I follow all the instructions and clean it regularly/check the pipes inside the machine. I’m really concerned :(
