Thanks for writing to health care magic.
Not to worry regarding your baby. Occasionally babies do not eat much and this may not be indicative of any thing.
We should not rely on skin touching for monitoring of temperature and should use a thermometer for the purpose. If our hands are cold
we may feel the baby to be warm and if our hands are warm we may feel the bay to be cold.
Not to worry if the baby has one odd viral fever
. This is how the baby grows up.
Hope this helps.
