I think children can start making decisions by themselves in their early teens, around 13 to 15 years old. At this age, they begin to develop critical thinking skills and start understanding the consequences of their actions. They also gain more independence and responsibility, which helps them make decisions about their personal interests and hobbies. Parents can still guide them, but it's important to allow them some autonomy to learn and grow.

I think children are better equipped to make decisions by themselves in their late teens, around 16 to 18 years old. By this age, they are more mature and have a better understanding of complex situations. They can make important decisions about their education and career paths. Additionally, they are legally allowed to make certain decisions, like driving, and are more capable of handling the outcomes of their decisions.

It really depends on the individual child. Some children mature faster than others, so the age at which they can make decisions varies. Cultural and familial expectations also play a role in determining when a child is ready to make decisions. Different decisions require different levels of maturity, so parents should assess their child's readiness on a case-by-case basis.
