My baby and i took an one hour flight. He drank his bottle(nan2) on the flight and everything was fine. When we landed he had his porridge. When it was time for the next bottle he refused the bottle. I tried all kinds of cups/bottles but had no luck. He still sucks his dummy. I give him formula with a spoon or syringe but he fights it too. He has been on Nan 2 a week before this started. He has no fever and still love eating his food. Is it a phase? Is it the switching over from nan 1 to 2?
