Invention of the Day
A drone that replaces a pram. Stick your kid in it and it just follows you (well your phone to be exact) around.
Imagine if you lived in a Parisian block of flats with no elevator. You could just open the window to allow egress of the pram-drone and then whip downstairs to join your kiddie at the pavement.
