My daughter used to do this and it drove me batty! Turns out because her hands were so small, even the 00 size was too big for her and kept sliding off of her fingers and the Velcro would loosen. She switched to buckle grips, drybands which fold over top of the grip and most importantly (per her - I know nothing about grips) started using rubber bands on the back side of the grips to hold the finger portion in place. I can't fully explain how to do that but I know that it really helped her out.
