At risk of being pedantic, inattentiveness comes in different varieties. For example, there is a difference between a grown man walking into a lamp-post while in public and a child misjudging the distance needed to take a step. One of these types of inattentiveness is vicious (the grown man, who by all accounts should understand how to 'look where he's going'), whilst the other very likely isn't vicious (children, quite innocently, do not have the same spacial awareness as an adult-- not by vicious defect, but simply by nature of their development).
As far as interpreting the visual in question, it didn't seem to me a vicious kind of inattentiveness given the age of the child. If it was a vicious inattentiveness, the I think I agree with your point.
