Final answer:
Infants are carried for longer in environments with more physical dangers, as this practice offers protection and satisfies their need for contact. Younger mothers have an increased risk of struggling with parental stress, potentially influencing care patterns. Technological advancements such as mobile phones can improve infant health through faster healthcare financing. Therefore correct option is A
Step-by-step explanation:
Cross-cultural observations have shown that infants are likely to be carried for longer periods during the day and for more months during infancy in environments where there are increased physical dangers on the ground. In such settings, the consistent physical contact aids infants in developing reflexes that help maintain a close connection with the caregiver, thereby offering protection and meeting their needs for constant physical contact. This practice can be influenced by various factors, including cultural norms, traditional gender roles, economic systems, and family structures. For instance, families in pre-industrial economic systems may require children to be more involved in chores and activities at a young age, influencing childcare practices.
Moreover, the risk of abuse or neglect can vary based on the mother's age, with teenage mothers more likely to struggle with the stress of becoming a new parent and exhibit less resilience. This increased stress can potentially correlate with differences in caring patterns, as younger mothers may find it more challenging to provide the consistent care and protection their infants need. Meanwhile, innovations like mobile phones and fintech services have been observed to positively impact infant health by enabling quicker access to financial support and healthcare.
