I have a 5 month old little boy and he usually doesn't nap during the day either. The only way I can get him to sleep is to rock him for about 15-20 minutes and then I can put him down for about half an hour. I never let him fuss it out cause he doesn't sleep any longer that way & I'd rather rock him for 15 minutes than let him scream for that long. The only time he sleeps longer than that is when he over exerts himself playing. He loves his jumperoo and he plays til he passes out or I won't try to put him down for as many naps and he'll take fewer but longer ones. Then he'll sleep for a good hour or two. He just has to be worn out first. I wouldn't be concerned about the crying out. We cosleep with our son & he randomly cries out and throughs his arms and legs out real sudden and then passes back out. I've had a lot of experience caring for young children and I've seen it alot.
