Awwwwwwwwww, BEST OF LUCK with your little Darlin today !!!
I am sure he will be FINE. Our 2 little ones have the run of the house when we are away and for the most part all is well upon our return. LOL Our little guy (nearly 7 months old) will find something to get into from time to time but overall they behave VERY WELL when left alone.
