When it comes to the best age for a child to start preschool, since every kid is unique, there isn't a one-size-fits-all answer. It completely depends on several factors like — a child's personality, developmental needs, family’s child care needs, and even family circumstances. Most preschools accept children at the age of 3, though some even start them as early as 2 or as late as 5. For children who are socially and cognitively ready, starting preschool around 3 years old can be an excellent opportunity to learn the required skills. It can also help children prepare for kindergarten and get a head start on their education. However, some children may not be mentally prepared to start preschool at 3 years old, and it's perfectly okay to wait until they are a bit older.
