There isn't a set age. There are signs that cues that you should follow. I've seen some kids potty trained by a year and some not potty trained until 3 1/2. GL
Of course, teaching a toddler to use the potty isn't an overnight experience. The process often takes between 3 and 6 months, although it may take more or less time for some children.
Also, some experts may recommend starting the process during summer because kids wear less clothing, but it is not a good idea to wait if your child is ready.
Here are some signs :
follow simple instructions
understand words about the toileting process
control the muscles responsible for elimination
express a need to go verbally
keep a diaper dry for 2 hours or more
get to the potty, sit on it, and then get off the potty
pull down diapers, disposable training pants, or underpants
show an interest in using the potty or wearing underpants
