Hello doctor,

My baby is 5 months old. I have given vaccine to her on 18th of this month, since then she was having fever every four hours the other day too. After that she is not drinking breastmilk and formula too. Now only drinks at night time while sleeping. What should I do?

Welcome to icliniq.com.

I understand your concern. Usually, vaccines are not related to decreased feeding. Fever might be because of vaccine only but not decreased feeding, it may be a sign of infection.

Is the baby dull or lethargic? Is there any recent Formula change? What about stools and urine, is it normal or less? Is the child irritable or is there any swelling at the vaccine site? You should definitely see a pediatrician if this persists.

Thank you doctor,

Urine is low in the day time. But passes stool normally like before. No change in the Formula. There is no problem with vaccine site. Only that she is not feeding.

Have you checked the oral cavity? Is there any lesion or white spot? You can try changing the Formula but infection has to be ruled out. Is she dull or active?
