My 1-month old son startles very easily when sleeping and frequently squirms around, even in a dark and quiet environment. I don't know if he's having a bad dream or what. This happens whether he's in my arms or in his cot, although he's a little bit more settled when in my arms. While sleeping he would startle or squirm every few minutes, and we'd have to SHHHH and pat him down. This would work several times, but eventually after no more than 60 minutes he would wake up crying. We swaddle him, play soft music, sing, hold him for 30 minutes, and do everything we can to not overstimulate him. We put him to sleep on his back and on his tummy under close supervision, same results. Please help. Thank you.
UPDATE: I have been keeping a sleep log for the past couple of days and found that he sleeps on average 10-11 hours a day.
