DS has been invited to a party tomorrow afternoon by a boy from his nursery. He doesn't have that much to do with the boy but does know him. The invitation was given to all at the nursery so I'm not sure who will attend. I've been told DS can stay alone (he's 4) and will be looked after or DH and DD can stay with him. I've told DH to leave him there if he's happy and collect him later. DH is horrified by this idea as I don't really know the family.
What do you think?
