Completely normal. It's instinct for most dogs to save back some food for later as in the wild they didn't often get regular meals and were always seeking and hiding food for later as in the wild the rule is survival of the fittest and canines rarely willingly share food with others, returning and moving it again and again as long as they smell other critter scent has been near it. They are often vigorous guards of their resources and goods.

They try to mimic that behavior in domestication with food, treats, toys(which are resources to dogs) or anything they happen to get that they see as a resource. Some of them whine and whine as they sense their hiding place isn't really "hidden" or adequate and is too close to others in the home, isn't deep or well-covered, so they are ill-at-ease until they move it again - and again - and again until they finally give up on it for a while and nap. So your baby stashing away her goodies - whatever they may be - for later is perfectly normal canine behavior and she will likely continue that for most of her life. Just be sure you are able to walk over to her "stash" and pick up anything you want without triggering a growl or show of her teeth. She needs to understand that you have unfettered access to her resources at all times from an early age.
