I just started running a new Dungeon World campaign and one of the players is the Druid. One thing I noticed is that he was changing shapes a lot. This seems reasonable, as the rules don't really seem to restrict how often the Druid can change shape (and it seems to be his main shtick), but it threw me for a loop to try to figure out what each animal form could do.
In regard to assigning each creature a move, in particular, the best I could come up with was asking what he was planning to do with the animal form and try to make the move fit that. This meant that the same form might have a different move when he shifted to it a second time (like, say, an eagle might have a 'watch for any motion' move when formed for scouting, but have a 'rend with claws' move when formed for combat.) Is that the right way to do this?
I did ask him what his shapeshifting is like and he said it's like becoming a fast-flowing liquid that reforms into the new shape, so it means he can change shape pretty rapidly on the fly. In one sequence, he became a mouse, hid in the Ranger's pocket, then later shifted to a small bird to fly directly out of his pocket and up to a branch nearby, only to grow into an eagle and defy danger to dart past some imps and rake the eyes out of a cultist. Which is all pretty cool, except I'm starting to wonder how I'm going to create suitable challenges for a character that can so quickly change its capabilities in the narrative.
The closest I got was luring him into a burrow as a mouse, where he couldn't change to a larger shape to escape danger, so I think Show a downside to their class, race or equipment is one of the main tools to keep the shapeshifting under control, though it's hard to think stuff up when the shape keeps changing so quickly. I'm also concerned that the speed of the shift means that even if he uses up all his Hold (and changes back to human), he can evade the consequence by immediately taking another shape. Especially since he's already established that he can become a rhinoceros.
How do I keep things interesting and exciting for the Druid, with his rapid-fire shapeshifting, without letting him slip out of any situation scot-free?
Side note that might be related to the above:
The players and I learned most of what we know about RPGs from a D&D 5E game that we played fairly tactical and min-maxy. I could sense that the players brought some of this attitude over with them, as they spent a fair amount of time in character creation asking about what the stats do and one of them asked "Is this choice on the sheet just description or does it actually affect the game?"
It was only our first session, so I think the players are only just beginning to grok that this game works very differently. That said, one of the things I've been doing is giving them a lot of narrative power and I think it's still their first instinct to try to optimize their capabilities rather than creating interesting drawbacks or limitations to contribute to the story. It sounds like that means I need to help balance it out, but still trying to figure out how that works.

As you say, shapeshifting a lot is reasonable. It's a thing the Druid can do and there are no (overt…) restrictions on the move, so adding some is a bad idea and will just take away what makes the Druid the Druid.
But it does have restrictions; they're just not obvious because the move is carefully taking advantage of restrictions that are baked into the rest of the rules. Let's look at them:
The Druid doesn't get to pick their form's moves
Don't ask what the Druid is planning to do! That's giving away one of your means of interacting with the Druid meaningfully. Instead, think about what is archetypal of the form and give it moves for that. An Eagle might have any or all of
An elephant might have
The form doesn't even have to always have the exact same moves list — you can tailor it to the needs of the situation that are obvious to you if you feel like that's following your Agenda and Principles — but by default, give non-fancy “this is just what an eagle does” moves instead of giving the player input.
The archetypal moves say something about the form. It says what it is suited to, and it should be you making that statement. It also emphasises that this is an animal's form, and it's good at doing things that animal is good at, rather than whatever is convenient. Let the Druid use the ability to shapeshift to look for convenience — letting them also help decide the moves they get is letting the Druid double-dip on the move's convenience.
Shapeshifting is powerful, and therefore it is Dangerous
Shapeshifting seems easy — just do the move and it happens! But it only seems easy when it's done successfully, because the Druid did it successfully. Constant, “on demand” access to such a powerful effect is a hallmark of the Druid, but that doesn't mean that it's wise for the Druid to use it like it's going out of style.
Misses are supposed to matter, and the more risky the in-world action, the more extreme events are on a miss. What's more risky than inviting the soul-shattering power of Unbridled Nature into your body to utterly erase your human form and replace it with an animal? Just imagine how that could go wrong. Misses are that going wrong.
I'm going to quote myself from elsewhere to explain this further:
That quote really states the case strongly, but then it was in response to a GM who was completely at a loss for how to GM for a particular Druid player. But it's a dial that you can turn up and down, tuned for exactly how dangerous the situation is or how carelessly the Druid was shapeshifting. This is the main dial that makes Shapeshifter not a “win button”.
Misses on Shapeshifter don't have to always be cataclysmic, because sometimes something else will be more obviously the best GM move to make. But making even a few misses demonstrate the untamed power that the Druid is allied with and tapping into will make the Druid's player properly appreciate and respect the Shapeshifter move (and Nature) and stop using it like a hammer for every trivial situation.
For your specific situation, I recommend a lighter touch at first, but still a Hard move — definitely lighter than the story above about How Elephant Was Eaten by the Darkness. Based on your Druid's particular shapeshifting idiom, on a miss maybe give them a hybrid shape the first time —
The Druid's reaction will almost certainly be to shapeshift again (whether straight away, or after dropping back to human form) as soon as possible, but that's “fine”, in the sense that they can make that choice — with its inherent risk of another miss. That's just one idea for a miss though — once you start thinking of Shapeshifter misses as Golden Opportunities to show a downside of the class or make other interesting Hard moves, you'll start coming up with all kinds of beautiful, situation-tailored GM move results for those misses.
Just by showing them that misses have (like they always should) meaningful consequences in Dungeon World, you'll put a bit of caution into their use of Shapeshifter in an organic, DW-native way.
