Infants social emotional development milestones:

By 3 months an infant is able to feel emotions such as being able to calm down when someone speaks to them or picks them up, looks at a familiar face,  and even smiles when you speak or smile at them first. The people who might seeing a smile often are adults that interact or are around the infant the most such as caregivers, grandparents, or baby sitters. Strangers might be receiving a curious stare or a nervous smile because the child does not recognise them. They are often spending their time trying to sort out who is who in their lives. (American Academy of Pediatrics, 2021)

Children began to socially compare themselves and also begin to go through social pressures such as bullying, peer victimisation and fitting standards. The social comparison often looks like analysing self's skills knowledge, and personal qualities. For example a male student might feel unworthy because they are not as athletic as others. Children who are considered popular are known to have good social skills and are also known to be friendly. Therefore anti-social children can also gain popularity by becoming tough or bullying others. When bullying starts to become a consistent issue students might begin to withdraw themselves from their daily activities and can also start skipping school. It is important that adults notice signs in bullying and make sure to address them early to prevent anymore serious issues.
