 [ Symptoms ] can a fever in an infant cause stunted growth  my month old daughter had a fever of 102 5 for a week straight we called our pediatrician everyday and they just advised us to give her motrintyleon every 4 hours until it broke they now are wanting to do x rays of her to confirm that her growth has not been stunted i just am not sure why i need to expose her to the radiation when we are able to measure her and compare her numbers to the growth charts [ Disease ] fever in a child not sure what age does not cause stunted growth so i am unclear as to the medical justification of the x ray unless the doctor wanted to get a chest x ray to rule out a subtle pneumonia tylenol can be given every 4 hours but ibuprofen is every six hours fevers are not harmful they are the body is normal response to fighting off infections usually viruses so if a child is over 3 months old medical provider rarely get excited about routine fevers
