Confinement Nanny

Hi mummies, when looking for confinement nanny what requirements do you guys look for? Heard too young not good, what age range should I look for? I’m planning to get nanny from PEM… Do nannies in PEM do baby sleep training? I heard some mummies try to do sleep training as early as day 1. Those who have past experience with PEM do share more about it, would love to know 😊
