I'm having problems breeding my Misdreavus. He currently knows Pain-split, Perish Song, Mean Look and Confuse Ray.

But his children hatch and only know Painspilt and Perish Song. Growl and Psywave are there in place of the other two moves. I want the kids to know all the moves their dad knows

This is in pokemon white, Misdreavus is a male. I tried breeding him with a Ditto a a female Misdreavus and get the same results.

Any idea what I am doing wrong?
