I just looked on Bulbapedia and Smogon, and neither has it able to learn Helping Hand. It does learn Follow Me, maybe that's what you were thinking of.
Yeah, you're right. I had been thinking of Follow me.
Or you could put it into the Daycare to gain a few levels. Be careful with Egg Moves, however, as they won't hesitate to delete Egg Moves for a "better" move.
It doesn't go by "better" moves, it just adds them to the bottom, and moves them all up. However, for breeding purposes, it stays with whatever moves had when it was deposited in the day care.
