If the temperature does not come down, call the doctor to see what he suggests. Most temperatures will come down in two to three hours with acetaminophen or ibuprofen products. The most important thing is not the temperature, but how the baby looks. If the baby is happy, playing, drinking, etc., wait for the ibuprofen or acetaminophen to work. It looks terrible.
Many moms take their own food and blend it up and give it to the baby.
If the baby eats it, then don't worry. I have never heard of that and see no reason why. There is nothing that will hurt the baby's eyes or anything. I give him pointers and tips to make things more interesting, but to no avail. He seems to have low self-esteem and says he's the worst in the class.
