Warming Grawnk's Heart
I don’t see how you can do it again. The achievement is already completed upon login after the first patch.
You can’t do it twice. It’s an account bound achievement and like most achievements it’s one time only.
Be careful what you ask for
ANet may give it to you.

I found Grawnk and the orphan in my Home instance. Upon speaking to Grawk, he asks for a certain Bloodstone delicacy. Upon speaking to the orphan, she/he thanks me for helping and completing the quest.
I only spoke to them because they spawned on my Wintersday Gift Tree.
