This review is dedicated specifically to the animation/visuals.
The characters are simple, yet cute and expressive.
The first-person scene from 0:08 to 0:16 was done frame by frame to emulate 3D. I bet that was difficult to do, but it was done using only outlines and looks really rough.
In frames 88-89, the mother switches poses without any in-betweens. She was holding a spoon in the former and not holding it in the latter. Where did it go?
She also lacks lip-syncing, which is a good way to indicate if a user is talking.
Outlines are really rough. It's not that noticeable to the human eye when the frame is only visible for 1-2 frames, ie. the baby crawling under the fridge, but people WILL notice it if you stay on that frame for a lot longer, ie. the mother looking at the baby crawl under the fridge.
I recommend you attempt to fix these outlines after you've drawn them.
