How does lyo classify the types of infant attachment in someone to watch over you?

In "Someone to Watch Over You," Lyo classifies infant attachment into four main types based on the work of Bowlby and Ainsworth: secure, avoidant, resistant, and disorganized. Secure attachment is characterized by a strong bond and comfort with exploration, while avoidant attachment indicates emotional distance. Resistant attachment reflects anxiety and clinginess, and disorganized attachment shows a lack of clear attachment behavior. These classifications help in understanding the impact of early relationships on later emotional and social development.
