Keeping the name Abdullah

Q: I want to use name Abdullah for newborn. Is it ok considering the child will not be able to give adequate care to protect Allah's name in his books, school papers, etc. To avoid desecration during growing up years bound to be thrown around, is it better to use another name or is it allowed?
