Final answer:
Having siblings is beneficial for children, but only children do not have many disadvantages in life.
Step-by-step explanation:
Yes, having siblings is beneficial for children but only children do not have many disadvantages in life. Siblings offer companionship, emotional support, and opportunities for social interaction. They can also help children develop important social skills, such as negotiation, cooperation, and conflict resolution. On the other hand, only children may have more opportunities for independence and self-reliance, as they do not have to share resources or compete for attention.
