Hello doc My 1 month old baby only sleep 8-10 hours in a day and do sound like clearing throat and spit up very much curdled as well as plain milk after 10 min of burping. Usually spit up comes after 1 to 2 hour of sleep and makes him awake. After every half hour of sleep he start making sound of clearing throat,face become red and try to push something every time he sleep an then he is unable to sleep
