There is no legal age when a child can be left home alone and it is down to the parent/guardian/carer to make that decision. Common sense would suggest that the child would have to be of an age where they could look after themselves and that it would not be appropriate to leave a young child for long periods of time or during the night.
No, there is no legal age for babysitting. It is the responsibility of the parents using common sense to make the decision. It is worth bearing in mind though that a child under 16 years old cannot be prosecuted for neglect or ill treatment of children in their care. The parents/carers/guardians would be charged in that situation. However, any person who is 16 or over and who has responsibility for a person under that age could be prosecuted.
