Jennifer Garner attempted to drop off her son Samuel with the nanny before heading to the movie set today, but her baby boy was less than thrilled and erupted into a bit of a tantrum over leaving his mommy. Aww!

The actress is currently busy filming Alexander And The Terrible, Horrible, No Good, Very Bad Day with Steve Carell, but it seems the littlest Affleck was the one having a no good, very bad day!
