i'm sure others will give you plenty of ideas here.
personally i'm a night time wriggler! i just put mine in a sock and have it in the bed next to me, mostly i scoop it with me when i move around.
could you try one of those stuffed animals that double up as a place to keep your night shirt during the day? i'll bet placing the pump inside one of those would solve it for sure, as she could cuddle up to it at night
