Some you will loose, but not as many as you might think. The trick is mostly getting the wood thin enough so that it can move as it dries and good placement of the work inside the log, a bit of warping isn't usually a huge problem unless the wood is really squirrelly (like madrona which you have to more to to keep it even vaguely true, cherry is pretty easy to work with though).
Past that there are a couple of tricks that the green woodworkers use to mostly eliminate the residual issues. Most of the time you can get by without doing any of this but it's fairly cheap insurance. Once you've roughed the pieces out, boil them for one hour per inch (measured in the narrow direction of the thickest part - so if the handle is the thickest part and is say 1/4" thick by 1/2" wide you'd boil for 15 minutes+-). This changes how the ligin is structured (in some way that I haven't figured) which stabilizes the shape and also opens up the wood structure some (mostly by removing sugars) which allows more even and faster drying. Secondly manage the drying speed so it's more even, for thin stuff like spoons and spatula I think the easiest is to pack it in fresh shavings (in a brown paper bag) for about a week then air dry. Rake them out of the shavings every day or so (more if the shavings are really wet/dense, less if drier/fluffy) to let the surface moisture flash of and minimize any mold problems. Where you are I'd probably go turn and toss the whole mess several twelve hours and try not to pack it very tight.
Basically all checking is due to some combination of uneven drying and stress in the wood. With thin pieces like this if you get to the wood while it's still dry and at least sort of follow the grain (which is easier to carve and makes the piece stronger as well) you end up with something that dries pretty evenly all by itself and can relieve it's own stress. Part of this is picking "good" pieces of wood, for instance you can figure that denser wood will shrink less than less dense so some attention to the inside versus outside of the log and planning the piece so the outside is allowed to shrink more. The down side of limbs will have the outside of the limb in compression whereas the top side had the outside in tension so the wood will continue behave like that (which is why the bottom of limbs are no good for bow wood but the top is). Ditto that wood shrinks radially so allow for some movement in that direction (or for a spatula consider quartering a piece so the bottom is more likely to stay flat as it dries).
You do also have to get the roughs cut out before they crack, around here that's somewhere between a few hours in summer and several days or maybe weeks in winter. When I'm not actively working on a piece best is to freeze it, or for short term wrap in plastic to keep it from drying until it's thin enough to be safe.
Bit of a ramble but generally speaking I haven't had to much trouble with just carving them except a couple pieces went weird shapes which I think I could have stopped by boiling in most cases.
