To do the baby sign for vacuum, tilt your curved, open dominant hand downward, with all fingers hanging loosely. Then position your fingers above the palm of your non-dominant hand. Now swirl your dominant hand around and a little forward as your non-dominant hand follows its direction, as if it is the nozzle of a vacuum cleaner is sucking up dirt.
We mainly use vacuum when familiarizing our babies with household appliances.
Use the vacuum flash card in conjunction with the floor and clean flash cards. To introduce your baby to simple phrases that point toward function.
