This may not be helpful because it doesn't sound like the exact same virus that my son had at 7 mo, but he was sick for about a week and barely ate during that time. It was so scary. I was sure that he was dehydrated so i took him to the doctor but they said he was ok. Even still, for at least 2 weeks following that cold, he wasn't eating normally. He would barely get down 3 bottles a day if that, whereas before he was drinking a minimum of 5-6. I was really worried about him, but one day he just was back to normal. Also, I hope your baby is taking some extra naps. A fever takes a lot out of them.
