My 11mths old baby keep falling sick every month, having high fever that will persist 5-7days. Could it be due to teething or is there anything I should be concern of? Thanks for ur precious feedback in advance.

Is your baby in infant care or is someone else in the family sick every month? When fever takes so long to heal it is usually viral fever. Have you consulted a PD on the possible reasons? Kids all go through a phase whereby they fall sick regularly especially when they start preschool. Does your baby sleep in air con room? And do you feed baby heaty food like snacks or toasted foods often? I heard that to boost baby immunity before 1yo you can give colostrum. After 1yo you can give sambucol
