My 10 week old has always been bottle fed and initially took it fine. Over Christmas he had a bad cough and cold and started refusing feeds, which I know if normal. But now he is better it is a huge battle to feed him. As soon as the bottle goes in his mouth he screams until I replace it with a dummy. I swap them over to try and trick him and this usually lasts for about 10 minutes before he gives in and eats. I know he's hungry but I don't know why he puts up such a fight! Any tips?
