Someone else on the forum mentioned ages ago about using a baby alarm to pick up the Occlusion alarm on a pump which seemed to me to be a really good idea as it will help you sleep better knowing that if the pump develops a problem where its not able to deliver insulin through the tubing and into the cannula ok, the Occlusion alarm going off will be loud enough to be picked up on a baby alarm next to Chloe's bed and if you have the other alarm next to you, you will hear it good and proper.
Also, go for the Flexlink 6mm set with about 80cm tubing and then that will give you more scope as to where to put the pump at night in bed. I tend to put it in one of those fabric drawstring sunglass cases (99p, poundland ones) and make a hole at the other end using a punch and then thread a loop of elastic or chord and hang it around my neck or use the same procedure with the silicon skin, then if I get up in the night, the pump comes with me and I don't have to worry about picking it up or having it falling on the floor. The other benefit is that if the Occlusion alarm goes off, I quickly hear it and also feel the vibration.
