Wait for daddy to be away from the turret/between turrets. Shoot it with AP rounds pistol round to get its attention. Keep shooting it whenever it starts to notice the turret(s). Run away until it stops noticing you. Repeat as necessary.
If I ever play it again, I'll give it a try.

Yeah, I was doing that the time I almost killed it.
