Problem is gas . BURPING is needed after every feed . make it a rule after feed keep ur baby on ur shoulder in such way stomach is pressed against ur shoulder . compulsory rule . It really helped me even if baby sleep keep on shoulder let sleep gets disturb but burp is needed.  baby will sleep on ur shoulder but donot let baby sleep without burp. It's 100% result. Without burp baby will not get satisfied and will cry due to gas . Imagine u eat and immediately ur in sleeping postion all food comes back to ur throat  medically called acid reflex . So make it rule 15 min shoulder time .and if experience tummy time when baby awake so tht nose is not pressed

5-6 mins if your baby burps . if baby doesn't burp then sit up straight already for 15-20 mins with the baby
