My fiancé’ is a super hard sleeper. When the baby is fussing he hears nothing. As soon as I wake him he will get up to help and he feels bad that he doesn’t hear the baby crying. I’m worried that if I’m not around and the baby is crying he will not hear him. The baby sleeps in a bassinet next to our bed right now and when we transition him to a crib he will be in the nursery, which could make hearing him even harder. Any tips to help my fiancé hear baby?
