These items can be in the sink or on a tray on a table.
The child is shown how to submerge the point of the bulb baster in
the water and fill it by squeezing and releasing the bulb. When the bulb
baster is full, he is told to move the point of the bulb baster over the
empty bowl and squeeze the bulb out.
When the child can use the bulb baster skillfully, he can learn how
to use an eye dropper, filling the dropper and releasing one drop at a
time. If he can count, he can release a given number of drops (he decides
the number). This skill is needed in the kitchen, in science experiments,
in nursing, etc.
An eyedropper is used in the same way. A small container such as a
bottle with a narrow neck, can be filled with water using an eyedropper.
