Makeup on baby?!?

So this girl I know has a preemie that was sent home from the NICU only 2 days ago. He was in there for 87 days... she’s puting makeup on him doing his eyebrows?! I personally would never expose my daughter to stuff like that at such a young age because you never know the type of reaction they could have especially after being in NICU for so long :( opinions?!
