My Milotic, Cecelia is very shy, too. I spent a lot of extra time grooming her and doing one-on-one training between her and wild pokémon. Feeling pretty and confident in her own strength came over time with that.

I haven't tried breeding her yet, but it's not completely necessary to breed a particular pokémon with the exact same species.
