A. hi your baby is 6 months old now at this age there can be 2 common reason one teething process causing gum swelling and pain and second is low hemoglobin levels in blood which cause muscle and body pain.give gentl e massage to gums and give a pacifier or small pieces of carrot to nibble and visit your pediatrician once
