Sometimes life’s most irritating problems have the simplest solutions. I was getting so annoyed with people (mostly the mailman + my dog barking) disrupting naptime, but I never did anything about it.
Then Mike suggested I close the front blinds and door. And I saw another suggestion on Offbeat Mama to put up a friendly sign. Duh and duh!
And hey… it works! Already have made it through a quiet naptime and found a package left on the front porch when we were done.
