Talk to the baby, take baby outdoors, introduce pets to baby. Try to involve baby with friends, family and babies around the same age.

All of the above. Plus parents must be sociable themselves as well. Kids love to imitate adults, they will follow and learn.

I go with him to visits some friends on my weekends but he is not interested in them his interest is on the other kids.

I interact with my baby alot . And when outside I make other play with my baby so the baby knows more people

My baby more sociable because I send him to nursery. So he have lots of friends to play and learn

My baby likes to be with other babies 😍 so on weekends I take him outside to meet other babies

Try talking to baby a lot more as then it comes in their habit of being social :)

I think all are relevant but siblings are important in the process as well.

try to talk , to always play with him and taking outside in the morning

I try socialising more and involving my kids in various activities
