My very sensible, responsible 13 year old wants to offer babysitting to our neighbouring streets. She’s always been fantastic with children and is saving towards a school trip abroad. I’ll go with her to meet any potential takers, and will be at home when she babysits as a backup for emergencies. She knows she’s not likely to get much interest due to her age but wants to try anyway. She’s looking at first aid courses at the moment. My question is how to phrase her flyer without making herself too vulnerable - she needs to state her age, do we say that I’ll be at home, and do we put a phone number or email or home address - or my mobile? Thank you for any thoughts/suggestions!
