If you're a parent who has to constantly tell your child the same thing over and over again, it may not because he or she isn't listening.
Scientists at the Hospital for Children in Toronto say it's because the child doesn't remember.
It's called "infantile amnesia," according to the scientists. It's due to rapid development in the part of the brain that stores memories. If you tell your toddler before the age of 3 to not do something one day, and he or she does it the next day, it might be because he or she has little memory capacity to remember.
The older children get, the better they become at maintaining long-term memories.
