Dislikes bottles suddenly

Nee

Hi Mommies,

My one yr old had cold last tuesday and he was fine. He had his yearly checkup last thrusday when he got his shots along with flu shot. He was fine untill this thrusday when suddenyl he got 102 fever. We consulted with ped and he said he doesnt have infections ( ears etc) and let him fight and increase immunity. This was on thrusday itselt . Now friday full day he had fever and today( saturday) too. In between he hates sucking milk from his bottle( we are using sippy cup nipple dr. Brown, and its been a month) . If i offer him milk via spoon he wil finish .. its time taking process to make him drink 4-5 oz via spoon.. any suggestions??
