My parents currently take care of my two DS's for four hours once a week when I work and before DH gets home from work. DS1 is 15 and DS2 is almost 12. My parents are due to attend a wedding shortly and DH and I are unable to get time off work. DH are discussing the option of leaving DS's at home alone. Both get on well and have said they would be more than happy with this. I would have no problem leaving DS1 but can't help but feel a little apprehensive. Do any other MN's do this? Am I being overprotective?
