Unfortunately, it's impossible to provide an exact number for how many toddlers have iPads. The provided reference only states that 11% of 0- to 8-year-olds use a cell phone, iPod, iPad, or similar device for media consumption. This is a combined percentage for all those devices, making it impossible to isolate iPad usage specifically.
Furthermore, the reference only provides data on media consumption using these devices, not device ownership. A toddler may use an iPad without owning it themselves (e.g., using a parent's iPad).
Therefore, we can't determine the specific number of toddlers who own or regularly use iPads based on the given information.
