The Manuka Oil Balm can mix in with some sudocream. It will bring the redness down and help heal the raw skin. Manuka has its own antiseptic and inhibits Candida which is a common yeast that causes fungal infection in moist, humid areas. As they are just 6 weeks old, I would mix half and half of Manuka oil balm with sudocream. At about 4-5 months, you can probably use it without diluting it, but the zinc oxide in sudocream is very soothing and also creates an extra barrier and prevents urine or other irritants from further aggravating the skin.
