I know a Jaime, used to be my boss, suits him perfectly & I never thought of it as a juevenille name.
I agree with most of the ladies on this one - if you like it - who cares?! I think you'll find that whatever it is will come to be the perfect choice & your child may even be protective of it, proud of it... happily correcting people that call him Gregory instead of Greg for example, all that does is make the person addressing him feel like a bit of a dork lol.
I am the opposite, I have a long name that can be shortened but I abhore the nickname these days. (Preffered it in my youth mind you!!) Long story short, you can't please everyone but the most important thing is how you feel about it, good luck coming to a decision!!
