Swing sets can be enjoyed throughout most of childhood. You can start with a baby swing when your baby can sit up, usually around 7 months old. When they reach the maximum height or weight listed by the manufacturer, make sure to switch them to a big-kid swing set. There's no specific age at which a child should stop playing on a swing set, as long as they don't exceed its weight limit. "Many children continue to use swing sets well into the elementary school years," Schwebel tells Verywell Family. "It is healthy for them to keep playing on swing sets as long as they want to."
