Help Me Out

I'm going to start a new thing. It may not be weekly, but it will be an occasional thing. Help Me Out will be where I ask you some questions, and you can humor me and help me out!

Jack (that is what I'm calling him this week *wink*) has been a horrible napper lately. He will fall asleep nursing and wake up immediately upon putting him down. He takes cat naps. Ten, maybe twenty minutes if I'm lucky. In order to get him to take a good nap during the day, I have been putting him in bed with Alice and me, and nursing him until he falls asleep. Then he will sleep for about three hours, BUT only if I'm lying next to him for a good part of that at the beginning. So I usually end up taking a nap for an hour or so (much needed!). I then put him in the bassinet, which I warm up with a heating pad so it feels like I'm still there for a bit. Any ideas on getting him to nap better and quit falling asleep at my breast? I don't swaddle him, but maybe that would help. He does well at night mostly. I put him in the swing, and he will go anywhere from 3-5 hours with the occasional longer stretch.

Alice, also, has been napping/sleeping poorly. She has been getting about 8 hours of sleep at night, and a two (sometimes three) hour nap. She really needs more like twelve hours of sleep a day. She will fall asleep for twenty to thirty minutes, and then be up for a few hours before actually napping (which means she goes down later than I'd like) and the same thing at bedtime. Tonight she went to bed with Sean (about 9:30) so I'm hoping she will stay asleep until morning. I think me lying in bed and being awake is what is interrupting her sleep. If Sean is here, I can stay out if the room until I'm ready to sleep, but if I'm the only one here, she won't stay in bed unless I'm right there with her. Any ideas for her?
