There is no magic age to start potty training. It varies for every child. Don’t compare your child to any other… every child is different! They learn to walk, talk and eat at very different times and the same goes for potty training.
Most children gain the necessary physical and cognitive skills between 18 and 24 months of age. But remember, you can't force your child to use a potty. If they're not ready, you won't be able to make them use it.
Wheter the start of potty training comes earlier or later for your child, you’ll get your cues on “when it’s time” from your child.
