Are batteries required to operate TruBliss products or do they plug into the wall? Can the Journey 3-in-1 Bassinet be removed and carried with my baby in the bassinet? Do I need tools to assembly TruBliss Products? How do you operate the Evi Smart Bassinet? How long should my child use the TruBliss bassinets? Is the canopy removable on TruBliss Bassinets?
