Re: separate species, I don't believe that's actually a requirement to meet the conditions of parasitism per Oxford Dictionary. A parasite is defined as "an organism which lives in or on another organism (its host) and benefits by deriving nutrients at the other's expense." -- Without getting into the emotional connotations of calling a child a parasite, it certainly does meet the Oxford Dictionary definition.
Re: bad for the creature, hyenas give birth through their clitoris. I'd suggest that's not great. Children cost an average of $233,000 to raise. That's certainly not great. That doesn't take into account career cost and opportunity cost of lost income. Sub-optimal too.
