Kid (5 y/o) wants to have a sleepover with a new friend he made. When his friend sleeps over, what should I do to make sure his friend feels comfortable in our house?

As far as getting medical records and such, I’ve got info from parents. Allergies, medical issues, etc. But what can I do so the friend that sleeps over doesn’t feel uncomfortable.Will it be weird if I hire an experienced nanny to take care of this? Is that bad that i pass on this responsibility to someone else? I’ll be there but just don’t know what to do. I’m thinking the nanny can do it better. via /r/Parenting http://ift.tt/2ppQYPC
