My friend and I are single parents and we use a Teenage babysitter who is very reliable for the occasional night out. She does bring her boyfriend who is a lovely guy, our girls get on with him and we are comfortable with the arrangement. She cannot babysit for us this weekend but she has suggested her boyfriend babysit our two little girls on his own. I feel awful as not sure I am comfortable with this at all. Am I being sexist? Is it appropriate for an 18 year old boy to babysit two little girls who are nine and why after typing that do I feel that the answer is definitely no when I would happily have him in the house with the girls when his girlfriend babysits. What do you think? People do hire Manny's after all! What a quandry!
