K.E.
My boy had a mini hunger strike when he got sick at around 12 months. It was very difficult to get him to eat for a while. He was happy and energetic otherwise. I would keep giving him his bottle whenever he wants it, maybe even throw in an extra one to make up for the calories he's missing. As long as he's wetting enough diapers and pooping occasionally and does not exhibit any physical signs of distress he should be fine. Also, if you find he does take any one food, keep giving him that even if it means bananas at every meal. :)
