Milk Consumption after poop

Hi mummies, let me know your thoughts… My nanny always claims that baby is hungry again after pooping and will need to feed about 60ml (a full feed will be 90ml), because baby exhibits hunger cue (but we don’t see the cue, baby is just awake that’s all). Despite feeding baby an hour ago, once poop means need to feed baby again. True? I’m doubtful because my hubs and I managed to put baby to sleep instead of feeding again. Sometimes I just feel that baby is tired and wants to sleep..not because she’s hungry. My baby is 7 weeks and is on breast milk.
