My DH in sleep deprived state accidentally got some tap water into a sterilised bottle, 'rinsed it' with some mineral water to clean and then put formula in. He mentioned this just after I had started feeding the baby. I stopped and started again with a propery sterilised bottle but she had already drunk a little bit. At the end of that feed she brought most of it back up. Since then (4 hours ago) she has barely fed and shown no interest in doing so. Have we given her a bad tummy from the bad bottle? If so what should we do? GP is calling me but taking his time and am getting in a state here! Any help much appreciated thank you so much.
