Sometimes Bart's father is attentive to Bart's needs, but sometimes he will ignore Bart. The way in which he responds to Bart is very inconsistent. At 17 months old, Bart clings to his father, but he is just as likely to ignore his father if his father tries to play with him. Bart becomes angry when his father leaves, and he is difficult to comfort upon the return of his father. What kind of attachment is this?
avoidant
disorganized
resistant
secure
