The law does not specify an age at which parents can leave children alone, but those who do can be arrested and prosecuted for cruelty and neglect if it places them at risk.
Figures provided by police forces in England and Wales following Freedom of Information (FoI) requests showed that 30 of those arrested were released without further action, 24 accepted a police caution and 19 were charged.
In other cases, investigations were ongoing or details of how suspects were dealt with were not available.
The issue of whether, at what age and for how long parents should leave children alone for has repeatedly sparked controversy.
High-profile cases range from parents arrested after leaving children for a few minutes to a mother who was given a suspended sentence after she left her children at home while she flew to Australia for several weeks.
''The government claims that the judgment as to whether it is right to leave a child home alone is made by the parents. However, in fact the judgment is made by the police and local council workers.
''Potentially, someone who leaves a baby in a car seat in a petrol station could face prosecution. Similarly, whereas an eight-year old can be sent to go swimming or to the park on their own, they are not allowed to stay at home (alone). There does need to be more clarity on this.
I really don't think Social Services will be hammering on any doors because a child has had an accident, unless the parents are already under investigation, sorry.
