I don't see Revoltech's figures as "toys" exactly: they're designed for poseability and accuracy as well as targetting a customer who usually can't afford or doesn't have enough room for Hot Toys figures. Sure they can probably take some abuse but not really rough play.
That being said, I used to always work over figures I bought when I was younger, working out how their joints move and how all the accessories fitted together. I used to always reinforce loose joints with glue and touch up the paint jobs too. Now that I'm older, I.. I'm still doing that. Funny how that works.
Unless your niece is the careful type, I would probably keep the Revoltech Pred safely on a high shelf or hidden away. On the plus side, if she does end up damaging it, the fairly low price of Revoltech figures means that you should be able to replace or repair it without much heartache.
Oh, and on a side note. Not to sound rude, offensive or anything, but please try to use full stops to punctuate your sentences. Long paragraphs made of one giant sentence give people headaches.
