This is adorable :) My unsolicited advice to The Agrestic's: No matter how big your guys get, keep giving them those good night hugs and kisses. Each of my sons still checks in each night for a hug and a kiss on the head before going to bed. I don't know many 21, 18 and 16 year olds that still do that, but it makes me one happy mama!
So glad to know that it can go on like that for years. That adds up to a whole lotta hugs and kisses! You should be a very happy mama!
