I don't want to be overbearing, but I want to at least be some kind of helpful; so I stick to only nudging during the close calls. I can tell, now that she's actually Hooves-In-Canterlot, her nerves are starting to spike; so my nudges also serve as a reminder that she's not alone. I think the smile she gives me every time I poke her back or her side means I'm doing alright.
