guardian angels?

Cardinals are said to symbolize hope, joy, health, and celebration. it's also said cardinals appear when angels are near. for the past weeks a pair are cardinals stay outside of my sons room, all day, every day. They'll either perch right on the window, or right on the branches outside. May just be my hormones but it's made so emotional and gave me so much comfort since learning this, that our baby boy is already being guarded and protected by his many guardian angels.
