When my granddaughter was born her older brother was 2 and a half years old. The day after DD brought Lila home from the hospital, Davis started getting jealous. DD had explained how she had milk in her chest, and she would be feeding the baby that way for a while. She started to nurse the baby, and Davis tried to climb up in her lap. DD told Davis that he had to get down because Mommy was feeding the baby. Davis got very thoughtful, looked closely at me and said "Nom Nom gots big chests, why can't she feed the baby?" We laughed until we cried.
