Hi
I had a simular problem with my children. I used the angelcare movement sensor monitor. It will sound an alarm if it doesn't feel any movement (included breathing) for 10sec. The sensor pad is very sensitive so they don't need to say on the pad. The pad is placed under the crib matress and their is a montior for the babies room and for your room. You can set the montior to make a little sound every movement or you can turn that feature off. This was my life saver I could actully get some sleep at night. We also started using it after my son went into a toddler bed because he would get up in the middle of the night and sleep walk. The alarm would sound 10sec. after he had gotton out of bed. We also invested in a t.v baby montior so that I could check on him with out having to get up everytime I was worried, I could just roll over and look into the montior and see him. We still use it with our children 3,4 and 7. I have placed it in there playroom so that I can keep in eye on them when they are down stairs playing and still get something done. I got both of these items at toy r us/baby r us. I hope this helps.
