DD is 16 and will be a senior this year and working this summer. DH and I are taking the younger kids on vacation next week and my 16 year old will be staying home and wants her boyfriend to stay at our house. Her boyfriends parents are ok with this and I think husband and I are going to let them. They are both great kids and she is on birth control and they use condoms so pregnancy is not a big concern. Plus my mom lives 3 doors down so she can check on them in case of emergency. Has anyone else been through this before?
