A milk rash is most commonly caused by the baby drooling and the drool causes the babies skin to get a rash.
The milk rash can also be caused by the milk in the babies drool that could be leftover in his or her mouth when they drool which can then lead to the milk rash on the baby.
Sometimes babies may be allergic to certain brands and types of baby formula which can cause them to break out with a rash as well.
Most milk rashes go away on their own without any treatment and when your baby drools a lot you should wipe their face off with a baby wipe or wet washcloth.
Keeping the babies face clean and free of drool can help prevent the rashes including the milk rash.
Milk bumps on babies is basically just acne that shows up on babies skin due to clogged pores.

The milk bumps on babies are caused by blocked skin pores in the baby and milk bumps or baby acne can appear on the babies face, nose, chin and even the babies cheeks.
They are not harmful and usually clear up on their own.
There's no way to prevent the babies milk bumps and no reason to really need to treat it because they do eventually go away on their own well before the babies 1st birthday.
