My son (5 months old) adores his older sister. She walks into the room and his face lights up. When they are in their car seats (his backward and hers forward) I can see through the “spy mirror” that he lovingly gazes at her and generously laughs at her crazy screaming his name to get his attention. He even tolerates it when she sits on him and of course when she gives his tummy raspberries he heartily responds with a guttural laugh.
I just hope this adoration, love, affection and closeness lasts …
