What are safe touches?
Also asked, what is unsafe touch?
It is an unsafe touch if someone touches you on your body where you don't want to be touched. It is an unsafe touch if a person touches you in a way that makes you feel uncomfortable.
Then, what are good touches?
For children, "good" touch is touch that cares for them, that is necessary for their health or safety, or makes them feel safe, or is fun. "Bad" touch is any touch that they don't want or makes them feel scared, or any secret touch, or any touch on their genitals or bottom, unless it's necessary for their health.
This is common and may, typically, be initiated as young as at age two (through to seven years of age). When these manifest, parents need to re-direct the child's attention, clearly informing the child about concepts like 'good touch' and 'bad touch'.
