use what you are comfortable with some stains could be milk stains discard what you are not comfortable with.
If it’s newborn clothes, it’s usually milk stains. I would just wash one more time and then use it.
it depends on you, wash it again and if you still see stains and not comfortable then don't use them.
Bleach then wash as per normal but don’t bleach for too long
it depends on individual..i'll avoid the ones with stains
i will wash thoroughly but if still have, i dont use
I will throw away if got stain on it.
