Final answer:
An adolescent client's positive mothering may be most challenged by emotional maturity, as they are still developing the necessary coping skills and emotional regulation needed for parenthood.
Step-by-step explanation:
The adolescent client's age may interfere with positive mothering due to emotional maturity. Adolescents are going through significant developmental changes and may be less capable of coping with stresses, such as those associated with becoming a new parent. Studies have shown that teenage mothers are at an increased risk of child abuse when compared to older mothers. Thus, as adolescents are still in the process of developing their emotional and cognitive maturity, they may struggle with the responsibilities of motherhood that require high levels of patience, empathy, and emotional regulation.
