Has anyone trained their newborns to sleep in crib/bassinet?? My son is 3w4d and he screams/cries as soon as I sat him down! Even when he is clean, dry, & full! He still cries! I sleep with him on my chest or on the couch! I never get any rest I'm so exhausted! I can't even sit him down to go to the bathroom without him screaming/crying! I want the safest thing for him which is bassinet and I want some sleep! What do you ladies do??
