Yes I would.
I often do polish and preetys on children as young as 4, so why not Shellac?
If the parent wishes to spend the money for Shellac on their child who am I to say what and how they want to spend their money on?
I'm not their judge and jury.
I'm there to provide a service to whoever wants to pay for it,and providing my insurance is happy I will do it.
