How do i determine and treat my infants fever? without a thermometer?

Thermometer: It is best to have a thermometer. A rectal temperature is most accurate, but ear temp of forehead is ok. Fever does not necessarily need to be treated unless over 100.5 f. Fever is a natural response to infection and just because your cold feels warm, they may not need treated. If treatment is needed talk to your pediatrician to obtain proper dosing for tylenol (acetaminophen) or Motrin since it is weightbased.

Overall status: I consider fever a desirable, natural way the body assists in fighting illness. For this reason i encourage parents to treat the whole child not the temperature. If calling into the service you will be asked about temp & get one for that discussion.But on the whole you can decide based on the discomfort level of the child.If grumpy, treat, if not, why bother.Focus on fluid intake=more important.

Old world medicine: It is possible to guess at a fever, but to determine temperature needs a thermometer. Many grandparents laid a hand on the forehead, but they were also assessing the appearance and activity of the sick child. Fever is a very powerful defense against infection and should not automatically be treated. Talk more with your pediatrician.
