The protagonist probably shouldn't be crawling if he or she is two years old.
Watching the video, there are times where it looks like the child could be walking, but then there's another point where you can clearly see his or her hands treading along the ground as though crawling. But by age two, a kid should be able to walk quite proficiently - and run, too.
They're also fairly good at talking by this point - left alone in an unfamiliar situation, a two-year-old's first instinct would surely be to call for its parents.
It's a neat idea, but I think the creators may be a bit unclear on what a two-year-old is capable of. Either that, or they're torn between wanting an infant protagonist but needing to provide the player with a more mature set of physical abilities.
