Hi make potli out of roasted ajwain and garlic , keep it under baby's pillow. You can also use BabyOrgano's cold relief roll on, its ayurveda so no side effects. You can check https://www.babyorgano.com?ref=339

Baby is too small for home remedies.. massage mustard oil on feet and palm... You can use nasoclear, nasal drop.. just speak to your doctor once.. steaming should be helpful if you can do it carefully..
