My 11 week old son is sleeping well at night and was until a week ago able to have a good nap in the morning, I have avoided putting him in his moses basket in the day for fear of him not going back in it at night. He keeps nodding off and within 10/15 mins he wakes himself up frightend and crying, someone has said it sounds like the startle refelx and to swaddle but he doesn't like swaddling anyone any suggestions ??
