The question to ask is really why does your 5 year old have smelly armpits. This is because this problem is usually seen in children when they are starting with puberty. So your child may have a very early onset of puberty which is called 'precocious puberty' It would be best to ask your paediatrician to see your child for this reason. In the meantime you can use a roll on deodorant that is suitable for sensitive skin and does not contain alcohol.
