Dr. Vaibhav jainFather of a 5 yr 9 m old girl4 years agoA. baby just 4 years old immunity boost should be natural
Vaccination at proper timing as per vaccine chart should be done for immunity against infections.
Any type of health drink like horlicks bournvita Milo boost etc is not going to help if daily nutrition is poor. Health drinks have lots of sugar and just flavour and should not b given at all to baby less than 2 yrs of age.
Give protein powders like graviva or proteinex only if your doctor recommends it.
Give all types of fresh seasonal fruits rich in vitamin C and vegetables and a whole some nutritous diet for best development of your little one
