Mom!

Most days, Dad picks up Jonas from daycare and they play around a bit until Mom comes home. But once he hears that garage door open, Jonas will stop whatever he's doing and position himself so he can see the front door...

...then it will be a look back at Dad to make sure that this is really happening...

...and when that door opens, Jonas takes off!

...and runs down the hallway to the arms of Mom, one of the highlights of his day. (Mom's too...)
