Hi
I was given a waist belt and holder for my pump, but as I toss and turn so much during the night I actually somehow ended up with the cartridge in the pump somehow working loose during the night and woke up to a shock....went to bed at 6ml and woke at 22ml and full blown panic, then discovered that the connector keeping cartridge in had actually worked loose......have now got an armband, one purchased and one that I made from the excess waist band of the original belt supplied.
Since having the arm bands, absolutely no problem -and I sleep with now't besides the duvet, sheets and hubby!! (and dog!!). Connector hasn't come loose again at any time, still a puzzle what actually happened that night, but can only put it down to me moving so much, as I definitely do the connector up well.
I was absolutely worried stiff about sleeping with pump, and this was the best solution for me, as I also kick my legs up and down all night, constantly moving and sleep talking and crying out in pain. So if I can manage it, honestly..nothing to worry about.
