Depending on the apps, you could make some age assumptions of the kid too. Even more, perhaps extrapolate the number of children in the household based on the age-ranges of the apps and the behavior of how they are using the apps. A 3 year old and and a 5 year old are going to have very different usage patterns. The number of children and their age ranges could be a very important metric when considering targeted advertising to the parents. The fact is, this information is used against the consumer to manipulate them into doing things they wouldn't otherwise do - click an ad and perhaps make a purchase. Any bit of information to further that goal will be used, even better if its information about the children since that's a major purchasing factor for parents.
