Thank you for your query on Healthcare Magic.
1 to 2 times is normal in infants and nothing to worry.
I advise you to feed the baby with exclusively breast feeds.
Mild rise of temperature is not a indication to delay the vaccination
and I advise you to go for vaccination after consulting and taking opinion of your Pediatrician
Some times dehydration
may present with fever
, so feed the child frequently and adequately to maintain hydration.
If the fever is persistent, consult your Pediatrician for basic investigations like CBP, CUE, CRP to know the focus of any infection.
Hope I have answered your query.
