Perhaps the stress of a new home has made him tired. Also, he would be more tired if he has recently had shots. Keep a close eye on him. I gave my baby kayro syrup once for the same reason...just to make sure. It did perk her up enough that I felt she was more normal.
A new home is more stressful for a little baby than we realize, I think.
