So as of lately my baby wont stay asleep in his bassinet. He moves around a lot in there like jerky reflex moves then it wakes him up. He wont go back to sleep afterwards, so Ive given in and started putting him in his bouncer to sleep. Its more snug and he will sleep for 3hrs vs 30 minutes ( in his bassinet) So why is it bad for babies to sleep in these? Im right next to him so I monitor his breathing and everything, I know babies should be on the back but i dont know what to do.
