Millenials who can ' t afford to have them . Seriously . I ' m a married Millenial , and we can ' t afford to turn the second bedroom in our apartment into a children ' s bedroom . We need a paying roommate in that space to make rent . Shit sucks . <| sep |> We have let our daughter sleep on our chests her entire 3 month life for naps . It ' s comfortable to her and keeps her from getting a flat head . It also counts as tummy time , which is important for muscle development . Your baby will feel secure and comfortable in this position . Just keep an eye on his breathing . You can also feel his pulse on his soft spot on his head if he ' s breathing softly . Sids is terrifying , but if you are supervising your son , there ' s no reason not to let him sleep on you . There ' s no way to tell whether or not your coworker ' s baby would have died in the crib on his back , because as horrifying as it is , that happens too . It took me weeks to accept that I couldn ' t stare at my daughter ' s belly all night watching her breathing . I have a motion sensor device , but now I only use it when she ' s congested or I ' m feeling particularly anxious . 30 , 000 people a year suffer brain aneurysm rupture in the USA . 2 , 500 babies die of sids the same year , just for perspective . sources b r a i n a n e u r y s m s b r a i n a n e u r y s m b a s i c s b r a i n a neurysmstatisticsandfacts
