My LO just turned 3 m on Saturday & ive been having trouble the past 2 weeks with his sleep his naps only last between 15-20 minutes unless he is being held 😩 he never was able to sleep without being swaddled but now he fights that & keeps trying to break free. But his hands always wake him up if he isn't swaddled. He used to always sleep good in his play & pack & just all of a sudden after I feed & sway/Rock him to sleep & lay him in his bed he wakes up within minutes. Please help ? I need suggestions/ advice as what I can do to help him get sleep without being held & swaddled since he keeps resisting.
